I mean come on, every game has hacks and glitches in the first few weeks but they patch it. You guys STILL think it's the same IW that made CoD4 and Mw2. Reason Mw2 wasn't fixed: They all left or got fired literally 2 weeks after Mw2's release. Now you all must realise that they are doing their VERY BEST to fix this game, with the major glitches and bugs as priority #1, with stupid things that don't even matter like the clan tag glitch last.
They HAVE been fixing things, they HAVE been doing things half of you scrubs think their NOT doing. They fixed going underground on Outpost, in the truck on Outpost, fixed the Super Speed and Slow-Mo lobbies (at least as far as I can tell). They fixed the dual care package glitch (not like that extreme one from mw2, you only get 2 cares, not infinite!). They actually ARE banning people, I had 4 friends on my friends list banned perma for constantly abusing the underground glitch on Outpost, and the dual care glitch.
So STOP complaining, they WILL fix it! I mean, these staff are complete scrubs! Their all scrubs straight out of Uni, give em credit!
