The only reason Qc is considered mandatory is for rez. If they'd simply reduce the cast time or literally make it instant (even with a 1min cd), the skill would loose a lot of its appeal (which is fine, I'd still take it for quick aoe shield). E4E simply needs a rework. It is just bad in most raiding situation and it's not like dungeons require it.

I wonder if they'll a dress some of the issue in 4.2.
I can't wait for the live letter
