Lol I wouldn’t be surprised if the OP was actually the shaman he’s referring to. But yes, the shaman was out of line.
both should have been able to roll, assuming they are both playing their optimal spec (fury warrior and resto shaman).
War could conceivably use earthshaker in Naxx. Can be useful in AQ and even tech packs. Its always just a meme for the shaman.
Imagine getting mad for losing vendor trash
