Infantry gameplay feels solid but vehicles need a complete rework.

Switching weapons and zooming in out or going from external to internal takes too long. Vehicles are too sluggish. By the time you switch to your coax, the solider you wanted to shoot is dead. 

Vehicle on vehicle kills are rare. Either you have no repairmen and are instantly killed the moment you get into combat, or you can sit there and shoot at each other for 5+ minutes until you get overwhelmed by RPGs. Vehicles feel very tacked on. The maps don't allow any freedom of movement. Its largely reversing back and fourth.
