I am sure I will get bashed for this but I really dislike grouping with them. Am I the only person who finds it annoying when they mez EVERYTHING? I mean you get a heroic encounter with 8 down arrow mobs you don't need them mezzed. With a full group the AE's can wipe them out pretty quick. I mean sure if you get 2 or 3 ^^^ mobs yea we could use mez then, but I just think its stupid in a full group to mez 1 encounter.
I guess I shouldn't blame the class, just the people who play them. The way eq2 is made they are not anywhere near as important as in eq1 (once again IMO).
