The problem with this game is; they nerfed one set of weapons, but left the rest of the game untouched. By default, this makes everything not nerfed: OP, or everything that was nerfed: UP. Before December 1st everything was pretty balanced, vehicles were fine because our infantry guns were on par with them, shotguns weren't that bad because our primaries could counter them, and the same with the pistols.
Now, however, they nerfed only the primaries for each class, but left the rest of the aspects like vehicles and shotguns etc, untouched. This makes vehicles over-powered COMPARED TO THE PRIMARIES. Who is going to choose to run around on the ground with a nerfed weapon when you can use vehicles that haven't been nerfed? That is the problem with this game. If you have a pretty balanced game, but then decide to nerf something, you have to nerf EVERYTHING else in order to keep the balance. They should have waited to nerf the primaries until they were ready to nerf everything else like shotguns and pistols, that is what I think was their biggest mistake.
They should make an ability that would allow infantry to stay undetected from the radar, and they should nerf the splash damage of the "Hellfire" missiles.
I hope you all understand what I'm saying: we had a balanced game, then they nerfed one part of it, so wouldn't that make the other parts that weren't nerfed over-powered compared to the nerfed parts?
