question... i have been reading about becoming unhittable and all that over in the big fancy theory forums and i havent been able to hit the ~104% mark that they recommend despite having geared and gemmed to the best of my ability thus far (working on SoH rep)... when i run the avoidance with stoneskin gargoyle macro from satrina's post i am at ~56%. i dont have any trouble tanking any 10 man content and my guild hasnt ventured too deeply into 25 man content just yet. so the question... how do i get ~50% more avoidance or am i spinning my wheels trying to get to "unhittable?"
even worse... did i completely misunderstand what i read and im worried about nothing?

here is the armory link.
