I did good parses with WotC and AotB, but now I got yesterday my 4 set and BW is almost constantly up. I think I'll try to swap to killer cobra, not sure thou is Dire Stable better than WotC.
It devalues it a bit, but I think you underestimate how useful it is to KC-DB-KC in a BW window, where you're losing focus pretty hard in a non-AotW BW.
