What happened to the tanks?

Why do they feel all of a sudden like they're 3x the weight they use to be and EVERYTHING is soooo slow to respond, Turning the turret etc feels like a chore now.

I'm not sure what's happened but season 2 has been such a fail, New map is very pretty but from a gameplay perspective its horrible..

In the new map you either be a sniper or a heli pilot. Anything else you will just keep on dying to a chopper or sniper..

and for the love of god,EA/Dice...please do something with Anti-Air its soooo weak!

9/10 its either a miss, Heli spams flares that revive too quick, Or they simply fly so low that it wont lock on, Even though its clearly visible and not something in front of it ie buildings etc.

I enjoyed season 1 and played all the way through, But season two so far makes me just want to NOT play.
