Would just like to comment, for those of you saying Mistweaver is "Broken" or bad, I feel your grossly overstating. Granted they're not as stable as paladins, but Mistweavers in the hands of a solid player can still remain competitive if not take charge.
Would really hate to be a low ilvl inexperienced Mistweaver right now. Do something wrong and you are oom. We are also sub-par single target healers and instances tend to be very tank damage centric. Sure in the hands of a skilled and geared player we do damn fine raid healing but Mistweavers may well be broken at entry gear levels come 5.2 changes. Paladin and Rshaman are great entry level healers. Rshaman cooldowns are just awesome and fun.
