I always thought it was really odd WAR got an Axe instead of a Great Axe, I really question the reasoning behind that. Especially since BST got an Axe as well.

Also, I was only enhancing his Ideas My own would be slightly different. Probably an Enhancement to Berserk that increases its Attack>Def Spread by another 5%, Warcry seemed like a nice idea, Maybe the final axe could increase duration 30 seconds, make it a 1 minute ability. in the same vain it could also add to Blood Rage, since it and Warcry are the same style (AoE, 30 sec, Do not stack with eachother)
