Dont know about perfecting this, but at T4 running a similar set up I can regulary tank for a small 4 man group. Level locked at 39 with max AAs I am pretty unstoppable, unless we get a hold of too many ^^^s. As long as I am smart about pulling though I can get through just about anything. I really wish we had an actual taunt or a rescue type ability though. Its not often I lose aggro but when I do I would love to be able to snap it back.
