Burnished Quel'Serrar BiS for EHP?
So now that the stats on the 25man version of this are out, it's 74 base stam (less than high end tanking weapons right now because they all have sockets), however the proc is 1550 armor.
I ran the EHP calcs when I saw this. Fully raid buffed (without inspiration) I have a little over 52k hps and 31000 armor (as a warrior). Based on this, 1500 armor (I was in a hurry and not at my home computer so I didn't pick off base stats) calculates to roughly 5400 EHP.
If this proc is 80% up time like the old one... then that's huge. Way better than a 30 stam gem. And that's not even counting the extra defense (which frankly I could care less about).
