The AK74U needs to be nerfed big time. It was balanced correctly in COD4. The fire rate wasn't insanely fast as BO, it had a smaller clip, and the recoil was still vertical, but larger. Now you can just run around with the gun and barely even try. I refuse to use that weapon.
They still need to fix the gun, and a few other things in BO. I'm still spawning in front of people, after they patched Nuketown, the only map I see is firing range, and the lag compensation has gotten even worse. The Treyarch forums have been a mess with people talking about that since the new patch came out last week. I've been sticking to Locale Only searches, which have helped a little bit, but it can be frustrating waiting for a search to finish.
