We will see in about 26 hours, it's all hearsay until then. Only then we can have a sustainable idea of what it will be like. Granted more so during beta and after, but this time, if the beta goes as usual, I have a feeling we will lose many of our own. This is the time that we've been waiting for, I hope it will not disappoint.
Those class blogs really have me excited. They've really changed quite a few specs for the better. Hell, Hunters and Priests are pretty much new classes.
I really have my fingers crossed. Shaman were my first class in WoW, and I would love to play one again.
Celestalon hinted during one of the discussions (I think it was the one with The Instance) that we might see an ability similar to Sundering that Thrall gets in Heroes of the Storm for one of the shaman specs.
