DPSing as a healer

[mp-please]

This is not work, no one is paying you to play, on the contrary. That argument would be valid if we were talking e-sports.

Change for school/college and tuition then.
The point is that everywhere people will tell you better ways to perform, even to how to drink a beer if you go to a bar.

But why ONLY healers? That's what I can't figure out.

Healing is the only job that doesn't have dps part of it's job. Tank classes generate some of their aggro based on their damage, dps classes well, dps.
Plus the whole healer stereotype attracts the same type of people, i mean the usual "i want to help everyone but i'm not confident enough to do more than heal", sylphie is a good example.

Hell, this is portrayed in almost every single RPG game/anime where every single healer is always a frail looking girl/boy (usually girl) that never believes in herself to the point it became a meme.
