I would suggest looking into more threat stats. You are currently 80ish hit rating below your melee cap, and you need more alot expertise, especially with 3.2 coming out where your frost blast can be blocked/dodged/parried. Increasing these will increase your threat signifigantly because your attacks wont miss.
