Played almost every Battlefield so you are so wrong on this one. Last Cod I played was like 20 years ago.
Tank is way too powerful. The turret turn should not be that fast. In real life the turret of a tank turns around 360° in like 10+ seconds.
Vehicle balance is insanely off in the game. Both tanks and helicopters should be nerfed so much more. The turrets for sure and the helicopter gunner cannon as well.
You should learn to play infantry and not being a tank only goblin. It is pathetic. Go play world of tanks instead. Everybody that is only playing vehicles ask yourself a question why? Because it is overpowered and puts you in a huge advantage. That is why.
