It's car surfer not Car Stay on the Car For As Long As you can without the mod. (And you already have a natural debuff on accuracy due to high car speed and suspension when you are turning in the car.)
Doesn't need a nerf if you really think its op use it yourself. (imo HL3 is better if you are using weapons you can use out of the window)
car surfer leaves you completely exposed to outside fire.
People think JG is op (its not its a close range powerful weapon) the spread fucks up your 2 shots after 10 meters and it takes 4-5 shots. Again, if you think its OP use it yourself.
People think ATAC is op, its a fucking assault rifle it has high firerate, deal with it that's how guns work in the real world, Again, if you think its OP use it yourself.
No one uses Kevlar Implants because its so shit, that's whats going to happen to all of these guns if you keep fucking moaning.
