JC = Three +41 stam gems. Also, the JC-only trinkets. I have Crab and Hare with +24 stam gems installed (that's like 2,000 health just in trinket slots).

I have zero pieces of Naxx gear and I have 32k health, 25k armor, 545 defense. Heck, I don't even have many heroic drops either... mostly crafted epics (although they're pretty good).

I love JC as a pally tank.
