AK7U- Black ops, overpowered?

People don't really understand the meaning of the word "overpowered." AK-74U indeed is a great SMG, better than the others in the catergory, even though I prefer the spectre or the MPL. However, it's not the fact that the gun is overpowered. Just as it was in mw2, many people used the UMP. UMP was overused, not overpowered. Sure, it's easy to maneuver, but it's certainly not overpowered. Ak is overused. Many people believe it to be the best gun, but it certainly is overclassed by assault rifles.
