Feels pretty fair, generally. Though the amount of burst damage from hand seems excessive at times, particularly in a meta where healing and taunts are somewhat rare. I've won a ton of games where I had a lousy draw, couldn't win the board early, but found a doomhammer and just SMOrc'd my way to victory in a couple turns.
I think the ability to combine attack buffs and windfury has generally been limited by Blizzard for good reason. Right now it feels like it's just too prevalent, between DH, Inara, Arid Stormer on the WF side and stormstrike & rockbiter to buff.
