Heres a video of Why Me doing HC Ragnaros.
Believe it or not, there is actually a Resto Shaman.
As unfortunate as it is, difficulty brings with it the need for proper setups and/or requirements to make some things into your favor.
However, some tweaks and a resto shaman is just as viable as any other, so could we please get rid of the "Resto Shamans are useless for t12" attitude?
You're giving shamans a bad name.
