Just to tangent for a second...
I really wish they didn't get rid of resilience. Back in Wrath, even though I sucked like a black hole at PvP, by the end I was nearly unkillable because I went for a resilience build.
This is why valour points are so important to casuals. Better gear allows people like me to overcome obstacles that skill alone won't.
So maybe I would step into a raid...if I had gear that overcame my lack of skill.
Okay, end tangent. Back on topic.
