I've played some battlegrounds as Arms Warrior today and started rediscovering this spec. This spec has serious potential of dealing high burst damage with the right set of gear and talents. I believe that haste as stat is useless on Arms Warrior, because it affects only the cooldown of Mortal...
BiS staff for Druid, Mage etc. Send me a message here with your offer and let's hope we can strike a deal.
