i did 50 today and this class is overpowered, after patch changes cc became long enough to kill 3-5 "elite" mobs at once, and with good positioning and ccing pvp is easies thing ever;) it wasnt like that in second beta but now, this class rules the world;)
CW doesnt need anything, after patch aoe last long enough to kill big group of mobs and even with with elites theres no problem. Imo its good as its now. I just did 50lvl with wizard and i can easily say that if theres anything else added to improve cw itll be overpowered and needed nerf.
