Its not a problem if a Tank uses their tanking stance to build aggro before going into DPS stance. I did it fine when first starting out and with my raid group rocked the i270 slaying and pulled in sword. You cant avoid you enimity combo, you trade dmg for extra enimity so be it, DPS is youyr tertiary job as a tank (I am guilty of being a greedy fuck mind you) Ideally each tank should rotate one hate combo after dropping their tank stance after their burst phase. During pull useing 2 hate combos will normally keep you well out of reach of any DPS including Sam. the net loss is minimal overall. Also after the VIT changes in 3.2 keeping hate was harder because the VIT+ STR scaling nerfed out total output by 10% from when we wore full slaying. This is roughly comparable to that but is a straight increase overall.
