DPSing as a healer

[Taika]

So basically this just boils down to people and their "precious" time being wasted.

No, this boils down to being respectful towards your group members by actually contributing instead of doing nothing. What people are saying is doing nothing half the time is not an acceptable level of contribution or something that should be encouraged by saying "you're doing enough if everyone stays alive". Because very often doing absolutely nothing is enough for people to stay alive. Again:



And the related point is, that even if a person's active contribution of something isn't required to clear an instance, that's not a good reason to not actively contribute. You can clear any instance in the game with a BRD who doesn't sing or a tank who doesn't do any DPS, that doesn't mean that it's ok for them to not sing and not do any DPS, and most of all that's not a good argument to claim that they're playing well (or even well enough) if they refuse to do those things. Because saying that is actively encouraging bad play, and that doesn't benefit anyone.
