I haven't got my copy of the game yet (Slow mail FML) but I have a feeling my thoughts will be as yours. One of the only reasons I can't wait is because I have a feeling that CoD will do amazingly well in the competitive community with the updates they've been speaking about... I really hope it takes off and lives up to what I am expecting of it competitive wise.
I can certainly see just average gamers getting tired of the same thing.
The major complaints I've read thus far are all easily fixed by playing with a proper team and not doing "pubs".
