Didn't really read through 8 pages of replies... But, in answer to the OP question of what I want to see in raids...
Tanking that doesn't require also putting out DPS.
Healers that aren't expected to also DPS.
Basically, I want to see less DPS race. Less scripted boss fights would also be nice.
I loath healing in this game for the sole fact that I feel like I'm expected to DPS in addition to keeping the group alive.
I tend to get focused on doing one or the other, I find it difficult at times to do both.
I had a derp moment the other night. Got so focused on keeping one of the tanks alive, I didn't see the party chat going on, getting told to follow the rest of the party.
