Mazi, I am not saying they should do garbage DPS by any means. But I think in the general MMO design, pure DPS classes should always be on top, followed by the hybrids/utility.
Of course 25 mans are going to stack the higher DPS first and bring the hybrids/utility later. But they will still bring Spriests/ferals/boomkins because they have other amazing things they can offer other then lord DPS

I mean hell, lets look at where spriests came from...
Vanilla through BC they were literally called, mana batteries...
WoTLK they got a lot of DPS buffs/utility.
Cata they become decently competetive
MoP they are fairly competetive and only getting more competetive.
I think they have gotten pretty good buffs over the course of the games duration IMO
