I'm sure I'll get flamed for this opinion but I'm a healer as well as a dps. On my whm, I heal and if there is time I dps. I NEVER dps at the cost of someone not getting heals. Unfortunately healers are picked on if they do dps and if they don't. We can't win.
Right now tanks want to wear underleveled gear so they can "dps" which is rather laughable considering a whm can out dps a tank. I'm not saying this to add to the fighting but because it's true. What a lot of healers forget is that the dps jobs can out-damage a healer and keeping them alive is the smart thing to do.
Eventually tanks and healers may realize that SE is purposely making it so they have to do their jobs instead of dps. There are many dps classes they can play if that's what they want to do
