Why healing is broken and terrible, and how to fix it...

[Shurrikhan]

Either way, the way damage happens in this game is ultimately responsible for this situation. If healers were always (or nearly always) using their mana to heal, no one would even consider suggesting they DPS.

In dungeons that, too, would depend on the difference between the mana gained during combat and the mana gained outside of combat.

It would just be an added concern atop the duration for which tank eHP can be sustained against incoming damage (mass pulls tend not to, and have no reason to be, survivable on tank stance and heal spam alone), and may actually make DPSing even more vital, as regardless of the percentage of GCDs spent healing, the fight would become unsustainable, but now additionally due to mana.

Of course, making damage-dealing skills alone disgustingly expensive would do that for you. But expect then to see disgust.

And which instances would those be..The only time I can think of where extra DPS would be required is if you need to kill something very quickly and those instances would be very short.

You can clear it faster by putting in nearer to the same effort as everyone else. Or you can laze out and do it slower. Which do you think has more... ethical appeal?

You can clear a dungeon without dealing DPS. You can kill a mob with just auto-attacks. But should you? Is there any actual reason to do so? (Excluding the obvious masochism...)
