I have played this game now for more than 4k hours and can tell that this game is awesome.
The only big problem for me is the opfor armor which is too strong imo.
It is frustrating to shoot these guys from 300m with a MX. It feels like they eat at least 5 bullets until they finally die.
This doesn't occur in shooting Blufor or Independent since they don't have that OP protection.
It is easily recognizable that killing opfor guys is much harder due to their armor. Especially when they have a bullet proof vest.
It's no coincidence that opfor dominates in multiplayer.
I think it's a very good idea to nerf their armor a little bit. Many people in the community would agree with my post.
