Tank guns are useless anyway stulid. In general vehicles in this are a bit underpowered now. Take attack chopers, in bf3 they were way too powerful. Now theyre rubbish, some people will say thank god but for me personally its a loss for the game overall. Yes if dice could balance them properly, but they can never seem to find the middle ground. I sometimes wonder what idiots they employ, (drag of the street) to playtest their games.
