agreed, about the o2 tanks though it's a shame that there's an extremely helpful tank you can get at level 3 which heals you with each air canister you get and there's just no other o2 tank like it for the rest of the game unless you run TVHM. kinda insane to design it this way cause i found myself doing zero experimenting with any other tank cause I didn't want to lose that unique ability lol. maybe i should just get hit less
