Solution to healers not dpsing in dungeons

[Lildragora]

I recall a run of Omega v3. Party was topped off, regens up, Shield was up. Aoe went out, party got topped up and fey union was put on the tank. Tank was topped for the entire duration of it from 100 gauge and the co-healer just stood around doing nothing. Im all for keeping parties alive but there comes a time where people really should just use their abilities.

On a side note, this game as a whole, as I have experienced is never happy with healers unless it is a premade. People hate healers, you dps and get yelled at and you dont so you get yelled at, you get yelled at for 80% hp on tanks, you get yelled at for not letting regen do its job and be a over time heal or you get yelled at for letting regens heal over time. If the shoe fits, you suck and you need to stop. This even seems to follow through on development with a clear bias in some cases or at least a lack of understanding. From ARR to SB
