1) no map packs (ON time)
2) quick scoping (what it was) is dead
3) lagg
4) spawn system is crap (still)
5) PC's got the worst graphics out of all systems most failures also
6) Alot of patches (Cause they fail)
7) War is getting an advantage over your enemy whether it is hacks or camping doesn't mean you kill quick scoping
8) black ops should of had a beta so all of the glitches and problems would of been solved very easy before release
