I wish "people" would be clear that healing GCDs cost
personal damage. If you're playing "thoughtfully," you hit those healing GCDs because you think
the party's total damage will be better off for it, or is more likely than not to be better off for it -- in practice, meaning you think the party will actually clear versus wipe.
And, if the party's total damage
is actually better off because you hit that healing GCD instead of your personal nuke, why is it that the spreadsheet aggregator du jour fails to recognize that as a positive rDPS contribution?
Unless "people" decide that heals actually can have a positive rDPS contribution, the conversation is always going to be about damage neutrality and pushing everything into oGCDs (a la tank kits).
