I do... I have no idea what's wrong with me [lol] but I can't stick with one gun.. ADD maybe? Idk, shouldn't have anything to do with it, but I
NEED change in the game, and constantly switching guns/classes. And throwing the diff. attachments makes it even more scary

.
I use all guns pretty much, M4, FAMAS, SCAR, TAR, FAL, I don't use the m16 so much..
SMG: MP5/UMP/UZI, and I used to use vector alot, not so much as lately (But now that I had to think about it, I'll end up using it next time I play

, and I can't use the p90 for some reason)
LMG: RPD/AUG, and rarely the m240
Sniper: Intervention for quick scoping, and I used the WA2000 for a bit, and the m21 for even shorter amount of time, but I just started really quick scoping during th is prestige, and I just chose intervention for the hell of it, nothing against 50 cal, i'll prolly use it next prestige..
That's about it
