Make Sure You DW during BL that is a Big gain right there if you are not. I am also unsure of whether you should Gem ArP yet, Right now if you are make sure you are using heart Rhino (40 ArP food) and Elixir of armor piercing that way you are sitting more towards 1100 ArP . This may be the Crux where ArP and STR are the same but IDK, your over hit by quite some change i think Titanium Spikegaurds are better than your current bracers, Only because that 50 hit is literally wasted and the have 50ArP on them http://www.wowhead.com/item=47572 . Also pewrhaps even go back down to the 245 thrown http://www.wowhead.com/item=47659 dunno just spittballing. I do know that you shuold change your belt to http://www.wowhead.com/item=50995 as you are over hit and it gives a ton of ArP.
