There is only 3 problems that I see with this amazing game.
1. Too little variety of guns. Theres what... 2 SMGs, 3 ARs, 2 Snipers, 3 Shotties, and 2 LMGs (Forgive me if Im off a little)
2. Aim Assist does NOT seem to work. I dont know if its just me or what but aim assist doesnt seem to work. I have 20% accuracy though with no idea how it got there. Also, when your sniping you must lead your target at close range or it wont register.
3. The balance is a bit off. You dont get most good guns till level 13 and thats like a 3-6 hour grind depending if you bought LE. I know it is supposed to be a reward and what not but it seems unfair when I can kill some one with a rapid fire feline when all they have is a red dot scar.

But yeah these are just opinions so dont try to hate too much. Also tell your friends to get this game. More people need to know about it!

I agree that there is not a huge variety of weapons, but then there doesn't really need to be. If you think about CoD (particularly Black Ops) you only tend to use a few different weapons that you like, and the rest just get ignored. Also, I do agree that the Feline is pretty damn lethal, although I'm not going complain about that

YOu should post this in the feedback forum

The only reason I play Black Ops is for zombies. With mw2 though everything was OP so it was balanced. But lets not compare to cod.
