Goros, If you are ANYTHING but a bear, 275 health is better, mathematically speaking. Even though it doesn't scale, unless your stamina->HP conversion is 15.3 or better, of which only bears qualify (~16 conversion rate). Next closest is probably blood, I'm guessing about 12.2 with 3% from VotW, 10% from Kings and supposed new Frost Presence buff (8% stamina, up from 6%). I hope I haven't missed anything. Paladin tanks drop slightly to 12.1%, New Sacred duty (4% instead of 8%), Combat Expertise 6%, and Kings/Bosanc 10% (yes, I purposely ignored AD's 8.75%, it won't be on your paper doll)
And as stated originally, it's only 13 HP. Srsly.
