I agree completely, as a whole our class needs a lot more utility, I think Blizzard really messed up while creating our class.
Mistweavers are far too reliant on everyone being grouped up to heal, we're terrible tank healers, we have no utility and our major CDs are pathetic.
Windwalkers do mediocre dps and bring nothing to a raid besides DPS, there is literally no reason to ever bring a windwalker to a raid.
Brewmasters are good tanks but they have to do a lot of work just to gain the same mitigation other tanks have passively.
