Yoshi P to Mr.Happy "Heal DPS is not mandatory and no expectation for Healer to DPS!"

[Noata]

Well but that goes the other way around. Why isn't the healer helping the other 3 people to clear the dungeon faster? Mobs in this game don't hit hard enough for constant healing.

I think your missing where punishment and convenience are different things... wanting the healer to do the DPS's job for them is convenient for the DPS, Standing in AoE's forcing the healer to heal you because the healer didn't do their job for them is punishment

See where it is different.
