Does anyone use it at all??
The only class I see it benefit the most might be DK(with high dodge/parry). Otherwise, I dind't see a lot of tank with it since the proc is the worst proc ever. Unless I'm missing one mechanics in SoO that would benefit to be immune to death once in 2 minute cooldown.
Anyway, if your tank die, your healer did something wrong according to me.
I'm confuse why they dind't design a proc to mitigate dmg or buff your health pool.
And I didn't read a lot lately on avoidance stats. Does Blizzard wants avoidance to come back in force!!
