I think they're just not wanting to admit that healers are in fact in need of more damage spells to make things less boring. I excluded Sage because Phlegma at least is a full on damage move with no healing attached...and judging from the post above, they're trying to compare it with oGCDs you can't compare it to because they either require you to sacrifice healing (Energy Drain takes Aetherflow) or are used for the heal mostly. Phlegma is pure damage.
