Arms is my offspec and if my math is right I need 1260 arp for 100% cap while in Battle Stance. I'm at 1010 right now and could get to 1200 ArP if I would put in all ArP gems. With food buff that gets me to 1240 or 98.41% ArP capped.
So do I do that OR do I back off some of my current ArP and put in strength leaving in my Grim Troll 43% proc??
