What on earth O_o isn't that exactly what you are doing? I really do not understand your issue as this is pointed out:

That is all there is to it. The only reason people get on the back of healers only healing is because it means they are not doing much while DPS have to use specific rotations and done so at split second timings, so much so medium ping rates effect how much they can dps. So when someone is trying their hardest making these rotations and sees someone not doing much, it is pretty insulting.
My friend was doing ast relic (I posted this in the rant thread) on this group on her back for using clerics even though no one died. Then she had to heal bomb the mediocre tank to death because the SMN did not know what an AoE is or use AoE LB. After having enough with the SMN, who insulted her about using cleric stance, even though no one died once, voted a dismissal that happened to pass. After it did the other 2 admitted being a premade and called her a trash healer because the PLD, had to... *GASP!!!* use Clemency!
Then she was in a group for a long time in a1s pt, doing 90% dps, tossing out aspected regens to go with SCH shields and Essential Dignity whenever the SCH seemed needing a bit of backup to help them with their uptime with clearics. This SCH was replaced with an AST and people kept dying because that AST refused to heal at all. She wanted him to toss out a few essential dignity when needed like she does so both can have highest uptime. After a while the AST left on his own ranting about do not tell me how to play. After that they just let her solo healed and did fine and still tossed out DPS spells. The problem she has with co healers at times is that she expects help in a pinch so she is not spamming heals so much (I do as well to an extent, I had to ask for healing help in dun before), basically diving the work so both healers have the most uptime.
A simple example is , why should I have to cast 2 or 3 succor when both SCH can just heal the whole party when both use Indomitability? So there is more uptime for both healers when both heal for a split second, not depending on one to heal, one to DPS.
"We're all DDs now" I am not sure how endgame 1.0 was, but as far as 2.0+, sorry but this was always the case. Everyone in this game does some kind of damage, there never was pure roles here.
