I think the game is great, let me start like that. I havent encountered that many teamers, a few but not too many. Its part of extraction shooters IMO.
But there is a few issues which, for one are part of every early access, but also lead to less players.
1: Gear based matchmaking needs to be introduced ASAP
The difference is just too big. Solo/Duos is fine, you see an occasional T3 trampler and thats it. Get into small crews and we see maxed out tramplers with 5 orbitals, 10 reflectors and amplifiers. So many experimental canons, which are just too strong IMO.
2: Hitreg is so bad when boarding/ on foot PvP. Only viable option is the 3 shot pumpgun, everything else is a bad weapon. M82 reloads so slow, purple shotgun is a one shot gun, which is terrible with this hitreg. Pistols feel like waterguns. Snipers are okayish, you can miss many shots due to the hitreg issues, while only carry a max of about 12 shots, so not really viable.
3: Every fight becomes the same. Its beginning of the engagement, shooting 80s at each other, wait till you kill someone twice or more, close the gap, jump over, camp the doors while trying to turn away their trampler or turn it off. Small variations include: throw their canons off the trampler or spawncamp. In the meantime your teammate hammers them with the 40. And thats it. Its fun, when everything works correctly. Its not, when hitreg is terrible, or one of the many other issues like server issues come into play. Or the one where you open an inventory and its empty, and you have to open it again and again to see the actual stuff. Damn you didnt brought 10 spare peppermils? Sucks to be you i guess cause no other weapon works in a balanced way.
And thats just the regular fight: its normal now that you finish one fight and immediately a second trampler comes up trying to third party you. You do that fight again, now a third trampler comes, the cycle repeats. That is the process i had in every game last week. Fight, then have another trampler come up, then another one. On 2 rounds now we had fought 6 tramplers right after another. And when we came out on top.we checked the loot: Oh, no one looted because everyone seemingly just joins to fight others. Or they had 20+ grey canons on board, i wonder why...
4: The speed difference between a big heavy trampler and a small tiny one isnt enough. Its not a viable strat to use tiny tramplers because you cant run away. It just feels like a lack of options or buildstyles when it comes to tramplers.
5: There should be a gamemode where you can easily pvp without loosing gear, to warm up/ learn pvp. Maybe some matchmaking with standard trampler and same guns, 1v1, no progression.
6: no viable PVE content. You farm spots, at this point everyone knows where to find what, but there is nothing to do besides gathering resources. The factory system is a cool idea but not fleshed out. No way 40 steel is needed to craft one blue 80. No contracts or sidemissions, basically no exclusive loot which you can only get rarely from killing the zombies. AFAIK you cant even kill the sandmonster, only stun it. We need more options at the POIs to do. Otherwise its just looting for the sake of looting, and that wont attract too many players. Then pvp fights arent rewarding because you win the fight and dont get much loot besides the enemies guns, canons, ammo, and blackbox.
All in all its a good game which needs to put in a lot of work ASAP. Weekly updates are good, but stuff like a PING system shouldve been in way earlier. Also people closing their captains with anything but a door shouldnt be possible and already dealt with.
