I use it with Marathon, Stopping Power, and Ninja. The F2000 is then attatched with a grenade launcher, which reduces it's recoil. This is tagged along with akimbo usp's , because this thing shoots incredibly fast, so swapping to secondary is always a good idea. I generally use this class over a rushing SMG class cause it's alot of fun. Like you said, if used properly, it is a VERY good gun. It's just that some people are scrubs, so they run around with the UMP or ACR. They're good guns, but really require no skill .
