Well, according to link which can be found in sticky thread with all shaman changes it seems that Primal Elementalist could possibly remove cooldown of elemental totems... however noone can backup this and even if it would be true, it can change to almost anything.
However, I hope it will be true as having control over my dumb elementals was allways my dream. But having them permanently... damn, that would be something!
There is too many questions about this talent anyway like will caster's stat locking still work for elemental when u place him. Noone can these answer yet.
