Can we please stop talking about satisfaction and all that as if to truly speak for everyone? ... because you can't. There are plenty of reasons for people to be unhappy with one thing or another.

For me, I'm generally happy with healing until I have to deal with someone that throws things off severely. Does the DPS get a little repetitive sometimes, sure (generally on alliance), but adding another button to the mix isn't going to help anything. If they were to add more damage skills, they would still balance out to the same DPS and likely end up as a one-button combo because they're being very conscious of future additions down the road.
