They need an optional game play mode that will make it less "simulation" style of gameplay. The only differences would be you get a health bar similar to BF2 and there is no bleeding, also when you're dead a medic can revive you within 8 seconds if you are lying there for more then 8 seconds then you are dead and can't be revived.
Vehicles should also be stronger and beable to take 3-4 hits in Tank vs Tank combat. Really hope the developers can implement these features, it won't take long.
