Remove Glare, Broil, and any other DPS casting ability by healers then. Too many times have I been killed outright because the healer chose to DPS rather than heal. It's not like it was even a close one to kill a mob, I'm talking about just downright ignoring the fact of what your class is there to mainly do - heal. I've actually CHOSEN my PLD as my tank now because of this, and it's blatantly gotten out of hand.

Lately, I've been pretty much healing my way through raids (on AST) and yes, I actually heal people and do the best I can to mitigate the incoming damage. Yes, I even DPS. Am I #1 on DPS? Of course not, but I am contributing as a healer - just like everyone else that has your abilities is doing.

PLD and RDM have literally been a savior in raids and dungeons because the healer classes frankly have their priorities screwed up. You unscrew yourself on the priorities, I'll go back to a tank that isn't required to heal itself, or a caster that doesn't need to contribute healing.
