This is a good question. Starting in RoF, I actually stopped stacking Hagi/Hdex and went kind of oldschool with my aug approach. Highest AC aug(s) won out instead of strictly looking at heroics. I know heroics are nice and all, but I simpled my entire approach down to that. Keep in my mind, my Hdex is still near 500, so its not like im lacking anything in those departments by doing this. So this does make me wonder if its now AC > whatever heroics (where tanks are concerned) Anyone care to chime in?
