This isn't really a serious suggestion, just throwing it out there to see what the general public likes of the idea,

I was thinking of the powers of the higher members of the earthen ring like Earthmender Norsala. Seeing their powers in action in deepholme and Twilight highlands fighting off the elementals of Therazane and the faceless i can't help to think that they bind up an elemental guard close in resilience to them.
Ofcourse we can too to a degree but we need a totem to keep them there and they only last 2 min, what I would like to see, is either a talent or a Major glyph to make either our fire or earth elemental a pet or perhaps both and you can choose wich one to use since they're both so different. ofcourse this brings balancing issues but just as an idea and the feel of the shaman if this were implemented, what do you think?

(I realize the stupidity of having another pet class wich can heal :P)
