To reiterate. In case you haven"t noticed, by the way, more and more classes have been getting CC of some sort in WoW. Whether this is an overall positive or negative direction in PVP is a different discussion, but by gum golly a class thatfocuseson CC or debuffs, in a word, sucks. We"ve also seen what happens when you have powerful debuffs that don"t have overlap, leading to another intelligent Blizzard move with WotLK in giving buffs/debuffs of different names but the same, non-overlapping effects, to different classes. Some have the preferred flavor (100% uptime rather than say 95%), but they"re all available from 2-4 classes now. And that"s a good thing.
PS: In order to look to the future...we must understand...the past...
