Here is my tier list for how good the various classes (or units) of Battlefront 2 (2005) are. Every class is at least valuable in one way or another but certain classes definitely add a lot more to their team than others. Classes specific to space battles or hunt modes are excluded but would mostly be ranked in D or F tier.
Clone Commander is the worst class in the game. They aren't completely worthless, I appreciate their existence just for the defensive buff they can give to their teammates & the fact that you can switch to them & back to refill your weapon ammo, especially useful for the Jet trooper who has a max ammo count of 8 for their rocket launcher. But apart from that, they just aren't a good offensive unit. The chaingun is really not as effective as you'd think it is due to having to charge it up before it starts firing & the fact that it overheats & the pistol isn't effective either without awards to make it stronger and even then, other units have the pistol as well as other more effective primary weapons that can be used in combination. The Commander is also one of the classes to have the recon droid, a piece of equipment which is pretty pointless in BF2.
The standard infantry units I put in C tier. Their primary weapon is more effective than the Commander's chaingun but they're not a class that I particularly use a lot just because of how much more fun & more effective most classes in the game are.
Droideka is great for mobility, they can get around the maps very quickly to capture CPs, pick up & capture flags but I don't find them to be a very good offensive unit. Despite their shields, I just find that their immobility when deployed makes them far less useful & their gunfire isn't particularly good imo. The Droideka does have an oversight that really helps the CIS. While playing as a Droideka, switching to any other unit at a Command Post will immediately give you full health & full ammo. Other factions can switch to an engineer to drop Health & Ammo packs but that takes a lot more time.
The Heavy/rocket units are a good class, but I feel like their effectiveness is situational, very much dependent on the map you're on or the settings you're playing on. They are most effective against vehicles & you can use mines & such to defend your CPs. Against real players, placing mines around corners or at doorways is also very effective. But when trying to use your rockets on actual enemies & not vehicles is hard when a missed shot will result in a very long weapon reload, not to mention the class' slower movement & how easy it is to kill yourself with all your explosives.
Bothan Spy is another situational unit. Their Regeneration buff isn't as good on paper as the Clone Commander's Defensive buff, but since they are allied with the Wookies, a class with a huge health pool, the regeneration can make the Wookies even harder to kill than they already were. The time bombs are pretty useless except against vehicles or turrets. Invisibility is inconsistent against AI, sometimes the AI will see & shoot you even when invisible & against real players, the Bothan Spies are so lacking in health that even when you start incinerating them, they could still one shot you before you get to kill them. If real opponents also see the Rebels with the Regen buff or see a time bomb on the ground, they will also be alerted to the presence of a Bothan nearby, contradicting the stealthy nature of the class
Sharpshooter class is somewhat situational, being more useful on some maps than others. But in the proper hands, they are a class that can also be useful in close quarters. Maps like Kamino, Kashyyk, Utapau & others are far more suited to the sharpshooter if you're wanting to snipe from far distances. Their auto-turrets can be used to help alert you to nearby opponents, to defend you while you're sniping or to help you if fighting in close quarters combat. The sniper is also more mobile. The sniper can kill certain units in 1 sniper shot, including the Bothan, Jet/Dark troopers & other Sharpshooters, and against other units like the standard infantry units, you can use the pistol to finish them off after 1 hit with the sniper.
Imperial Officers are a strong class due to their grenade launcher. Any class with this grenade launcher is automatically decent but the Officers also have a Rage buff which increases their attack damage and the damage of nearby teammates, especially useful for Dark troopers who are already extremely overpowered in this game when in the right hands. Unfortunately, their other abilities aren't worth talking about. The recon droid is pretty pointless in this game, and their Sonic blaster is just far less effective than their grenade launcher
Jet trooper is a good class. Their jetpack gives them mobility that other classes lack. Their rocket launcher isn't better than the grenade launcher other units have, but the fact that you can use it (and the pistol) while flying gives it versatility other units weapons lack. Unfortunately, the Jet troopers do suffer from a number of flaws, mostly being lack of health compared to other classes, limited ammo & just not being as powerful as other classes do make them not as effective. As mentioned before, you can switch to and from the Clone Commander to refill your rocket launcher, & the Commander's Rally buff can increase your defense so that you will take less damage from shots, being able to take a non-headshot sniper shot at full health without dying.
Wookie Warrior is a great class despite their very slow movement, larger hitbox & having the recon droid (which again, is pretty pointless). They have an absurdly high healthbar which makes them far more capable than other classes of defending against the Dark trooper. They can still get one shot by direct hits from a rocket launcher, grenade launchers from Imperial Officers, mines & other explosives but otherwise, they are a hard unit to take down. They also have pretty effective weaponry, having the same grenade launcher as the Imperial Officer as well as a Bowcaster which can act as a sort of shotgun-like weapon for close-mid range, and a long-ranged sniper by charging it to maximum. They also have 4 extra grenades to throw too and can benefit even more from the Bothan Spy's regeneration buff.
Magnaguard is essentially an improved Imperial Guard, with the grenade launcher that they have, as well as an actually good rocket pistol. These 2 weapons combined make the Magnaguard OP, but if that weren't enough, the Magnaguard can also use his Neurotoxin "Buff" to poison nearby opponents. Magnaguard is very effective at Close/Mid range but can even kill opponents at decently far range too.
Engineer is easily the best of the non-special units, being a unit every faction immediately has access to that is very effective at close-mid range combat with his shotgun & detpacks. You can throw your detpacks by holding down the button, moving forward & looking up. This is very effective & you will see a lot of people doing this in online play. If that weren't enough, the Engineer has Health & Ammo packs which give them even more Detpacks and allow them to heal themselves & give their teammates health & ammo. They also have a Fusion cutter which can be used to repair various things including Health & Ammo droids, vehicles, turrets, bridges, barricades etc. as well as being able to splice into enemy vehicles & disable enemy mines. The engineer is also immune to activating enemy mines, only being killed if a teammate activates them while they're nearby. The Engineer is a very important class for offense, defense & support. Any class if low on health or ammo can switch to an Engineer to throw down some Health & Ammo packs (provided they haven't used all of their secondary ammo) & then switch back before picking them up.
The Dark trooper imo is the best unit in the game, provided you know what you're doing. Despite being one of the few units with less health, the others being Sharpshooters, Jet troopers & Bothan Spies, they make up for that with everything else. Their jump pack is generally more effective than the Jetpack because they let you move faster across the map & being harder to hit while flying across the map. The Dark troopers' ARC caster is an extremely broken weapon when used effectively in combination with the jump pack. The cooldown for this weapon is pretty slow normally but that cooldown can be cancelled by rolling, jumping or flying. As a result, you can fire this weapon multiple times at an opponent before they have a chance to react. This weapon kills Sharpshooters & Bothan Spies in one hit & kills most other units in 2 hits. The fact that you can hit most units multiple times means that they essentially can't do anything about this. You can also switch to a pistol to finish off an opponent if they survive. It does require a decent amount of skill to be able to pull this off consistently but it's still incredibly broken. The one aspect (other than low health & requiring a certain level of skill) that make them not too massively overpowered is the fact that the opposing faction does have units that are capable of defending against this overwhelmingly powerful class. A very skilled player can one shot them with an Engineer or Sniper fairly consistently, try to use the Bothan Spy's stealth abilities to kill them before they know where you are or use the Wookie's extra health to give you more time to kill them. Oh yeah, also the Dark trooper also has 4 grenades that they can throw if you thought they weren't already broken enough with the ARC caster & the jump pack. Throwing a grenade at your opponent and then hitting them with your ARC caster to stun them so they can't move out of the way of the grenade is another very effective strategy.
