Is there a video or anything somewhere showing how disc works in a raid setting? I can totally see it functioning well in dungeons, it makes great sense to me. But I cannot for the life of me see its worth or ability in a raid environment. I really like it in dungeons even at its crap tuning level on live (no doubt artifact starved) but if I can't be brought around to see the light on disc in a raid OR if it'll be mandatory to switch to Holy for some fights, I won't be playing a priest for legion.
