Their overall DPS is insignificant most of the time unless you have dual healers for the current end game content (it's actually better to not have 2 healers and have 1 dedicated healer due to DPS checks, but 2 healers provide more room for error). Your uptime for DPS is only maybe enough for a cast maybe every ten seconds provided your rotation timing does not match the attack timing of the enemy (swiftcast can help a little) combined with the big wall to wall pulls.
Wall to wall pulls will make it so that healers will almost never get a chance to DPS. They are focused on keeping the tank alive and have to watch the spikes from random crits or failure to dodge AoEs. The more enemies there are, the more likely it will happen. As long as you are doing wall to wall pulls, you are overpulling and not giving the healer a chance to DPS and it will force them to pay more attention to your HP than outputting damage. If you want a healer to DPS, stop doing wall to wall pulls so they can focus on something other than the tank's HP or the idiot DPS that runs ahead and pulls in more mobs. Mitigation alone is not enough when you are overpulling because the healer has to spend most of the time casting heals to keep you from dying. The most you save from a competent team is a few seconds unless you have excellent AoE.
Most of the time, you don't and the finishing time is roughly about the same. From my experience, I can finish a lvl 70 clear in roughly the same time as mass pulls, about 20 min average. If you have great AoEs, then it is going to be shorter for mass pulls since it is worth sacrificing healer DPS in exchange for the DPS class being able to AoE.
If you want to dismiss my argument, go for it. I don't really care.
tl;dr - if you want healers to DPS, stop pulling wall to wall. They can stop paying attention to your HP.
