Well tanking shouldn't be easy, but I think the threshold is getting a little too high for tanks who have to be married to VIT (on relevant content) to really keep up with hate. I'm going up equally geared tanks all the time, I can be in DPS gear and Sword Oath and unless they're fully focused on hate (WAR's included) I still end up stealing hate most of the time if I don't back off.
This is the 4th or 5th time they've made some kind of adjustment to Tanks Enmity potency abilities, but it doesn't address the overall mechanics when every major gear patch DPS will be getting another additional +25 STR/DEX over the tanks without some kind of adjustment that would actually scale more in line with the tanks stats vs' dps based stats which tank isn't focused on.
