Judging the balance in the CT by numbers can be very misleading. The CT attracts many very new pilots, who would probably be better served in the TA, as well as some of the most talented killers in the game. You can see 5 on 1 fights in there where 5 n00bs are gettin eaten up by someone like Shane all night. Sure it's 5 on 1, but those 5 guys are at a serious disadvantage. In general once you get 15 or more people in the CT things seem to even out pretty well, I find.
