considering the majority of people discussing healer DPS seem to admit "yeah, you should really only DPS because there's just not much healing to be done," whereas the devs have stated multiple times that they don't want healers to be dpsing a majority of the time, does that not indicate a flaw in the design that they are trying to achieve?

I love this game. I don't hate DPSing as a healer. But it often feels like why have a healer role if 80% of the time, I'm DPSing? It's a legitimate flaw in the game's design because it has been stated by the game's designers that they want healers to heal most of the time. It's not a matter of taste.
