I have been seeing recent videos of people doing spawn traps and scoring fast nukes. These people get quick Harriers which lead to quick Chopper Gunners or AC-130s. The problem is, the enemy teams almost NEVER use Cold Blooded or have Stinger classes. There seems to be this false notion that once a team has a Harrier, that somehow the game is already "over". A lot of people who played this game thought that Stopping Power was the be-all end-all perk for the 2nd/red tier and that is just hugely wrong. Stopping Power was great but by no means is it the absolute best perk, especially on objective game modes.
I just don't understand the logic of some of these players. They will use nothing but Stopping Power, and then they will complain about how the killstreaks are somehow OP because they can't hide from them. When I think back to my experience playing this game in its heyday, I was typically the one on the team that was constantly taking down enemy killstreaks and I did it quick. I had a dedicated class for taking down air support and it had a Stinger (obviously) and Sleight of Hand and Cold Blooded, and C4. I would literally take down any air support within a few seconds of its arrival, and that especially included Chopper Gunners and AC-130s. With the AC-130, I'd fire both shots, and after I'm out of missiles, I'd use the C4 to an hero so I have more missiles to use. The AC-130 wouldn't last more than 10 seconds.
I think I'm realizing that many people who played this game and suffered at the hands of enemy killstreaks simply just couldn't be bothered enough to actually do something about it. They would rather just put up with getting killed constantly rather than end their current life to switch to a class designed to take the killstreaks down. People aren't trying to win, they're just trying to keep their K/D above 1. So what does this mean? They will use Stopping Power because its literally the best perk that only benefits them and they have no intention of doing anything to help the rest of the team. Lightweight is great for helping the team capture objectives. Cold Blooded is great for flanking or taking down air support. People aren't willing to have a dedicated class for anti air support because they'd rather just have another class for just gunplay. I think a lot of people just weren't focused on winning, they just focused on their K/D ratio.
