Maybe the fact that they are trying to make Staff a more support based weapon means that they might be working on Greatsword in the background to be a more reliable two handed melee power weapon?
Not having Greatsword was a big disappointment for me this expac. Weaver, Deadeye, and Holo saved the experience for me, thankfully. Here's hoping that they come up with a really interesting and fun use for a Greatsword spec next time around.
