One thing you should change is replace Glyph of BT with Glyph of HS for a little more rage of HS.
2nd - NEVER MACRO HS EVER, dont be lazy use it when you need, with your gear you should be able to HS with even 30 rage, just gotta practice and time it out on a dummy.
Enchants on bracer's and shoulders should change ASAP. I recommend enchant hands and bracer's with expertise to get to the cap.
AFAIK, your meta gem is not active as I don't see a single blue gem in your gear, thats a 6% dmg loss on every crit which should be >50% raid buffed, so ITS A HUGE LOSS
You should use agility version of ashen verdict rep ring. Also you are at 78% arpen, you should really just go for 100% ASAP. Leather frost embelm belt has nice bunch of arpen on it or you can get belt of VDW 25.
I am wondering why you got 3 pc of t10 and stopped short of 4pc, any reason?? IMO either get the 4 pc bonus or Get the crafted legs and replace bryntoll for normal or heroic Ramaldin off DBS 10 to get expertise.
EDIT: If you dont already start using Landosuls spreadsheet for warrior DPS to chalk out gear upgrades.
