Healers that don't want to DPS are like DPSes who refuse to move out of AoEs.

[Hirmu]

A healer who heals isn't being carried.

You say this, but why do you think your opinion on this is the correct one? When would you say someone is carried?

By your logic, a tank who only spams flash to keep hate and uses damage mitigation is pulling their weight.
Similarly a MCH just autoattacking and putting down turret for dps is pulling their weight as long as the dungeon doesn't time out.
A healer who does just enough to keep everyone from dying is pulling their weight.

Can you please answer why these situations aren't all identical? Is it because a healer is called a healer? What about tank then? It's not called a DPS-tank. They're there only to tank, nothing else, right? Why can't I say "I'm here to dps and as long as I do enough to not time-out, I'm pulling my weight. You people and your arbitrary standards!"
