How are people finding the Warpstone in the release build?  In the betas it was handy for attacking fleeing enemies, for escaping from a sticky situation, and for shopping trips on Crucible.  I tried buying it today for the first time since release, and the only thing I found it useful for was the shopping.  The range was nerfed so much that unless you're a debuffed Rook, you hardly get to the target location any faster than you could walk.  A wand of speed probably would have been a better investment for catching up with people trying to get away from my Oak...

(EDIT: I should add that this isn't a complaint -- I'm just wondering if there's utility in this thing that I've overlooked)
