blade vortex gladiator duelist

I was thinking about a blade vortex build based on a max block gladiator in 3.1. The 3.1. tree and patch notes are not out yet but one can do some preliminary planning based on 3.0. I'm looking for some general tipps and feasibility estimates. From my personal play style it is more important to have a nice build from level 70-85 which is decent during leveling. Whether it is endgame viable at level 95 with 100ex gear is not that relevant to me because I won't get there anyway.
I put together a tree

Planning on the anvil and the surrender shield for uniques. Main damage from
blade vortex + brutality + controlled destruction + concentrated effect
for 5link I'm not sure, maybe iron will, maim (won't maim but still grant 30% more damage) or spell echo.
Additional skills are the block trigger skills with life gain on hit and curse on hit plus some movement skill. Auras can then be defensive.


Defense should be excellent with max block, life based, armor with a little evasion thrown in. I'm more worried about offense, there are not many physical spell damage nodes and none close to where the duelist starts.

Any thoughts and comments appreciated.
