This is all shamans new mini-heroism that will boost the entire raids dps, and we are 4 that can use it!
What we need to figure out is how to use it in our raids in MoP cos it don´t stack so we need to cast it one by one to gain the most of it.

-castingorder with some macro that w "the next"?  (when as many as 4 its hard to just yell in ts)
-depending on bossfights do we have time to use it more than once ? - are there some burst needed etc.

Shamans, what do u think?  Suggestions?
