Oh another thing Toon - probably best you don't play MW3 if you hated MW2, because a LOT of the really annoying things are back.
Overall, the weapons are much more balanced, and the grenades are much weaker (a good thing) as are the Twat Guns. BUT - but - the quick scoping has a tendency to drive me absolutely fucking mental. You know how much I hate it - the more I play, the more people seem to 'perfect' it. It does mean I get angry and therefore more determined to hunt down the tossers and get revenge, but I am so, so annoyed that they've brought it back - nay, ENCOURAGED it. Cheap, shite and bloody annoying.
A few glitches with leaderboards etc at the moment as well, but apparently there's another patch on it's way that'll sort that out.
Overall, I think it's definitely better than MW2, but I really don't think it beats Black Ops - purely because of the quick scoping.
