i had a shape shifting druid mine was a fire claw druid and he own most melee people but i couldnt hit casters because they just teled away before i could get a hit off. so what i am trying to say is that your build looks viable for melee duels i wouldnt think that you will do to well over all becuase when you are shifted you cannot cast teleport and since you arent a pally you cant shift charge to catch casters either.
