I'm not so sure that 5 Boomkins will catch on the way shammies have. While they do have some nice CC and damage spells, having to shift hout of moonkin form to heal is a pain. Moonkin form offers great physical damage mitigation, but spell damage mitigation is a bit limited (barkskin, and thats about it?). No fear bomb protection other than pvp trinket is really their achilles heel.

I think they would be great in PvE, but not so great in PvP...maybe for 5 boxers - 4 x shammies and 1 x moonkin could have potential though...

Cheers,
