Isn’t the Hall of the Novice for, well, novices? By definition it exists for lower skilled players who aren’t familiar with the game. I’m talking about in level 80 content, where players will be more familiar and skilled with the game. Lastly, they doesn’t the Hall of the Novice specifically tell healers to deal damage when there’s no healing required? That doesn’t sound like it ‘taking a backseat’ to me, more like always having it on your mind
Here is specifically what it says:
"When you've healed all there is to heal, there may be time to weave in some offensive magicks."
"But keep an eye on your companion! You should not be blasting if someone is bleeding!"
"Even when it's safe to attack, always keep one eye on your allies' health!"
"Another enemy threatens your party! You might try attacking this foe if your allies are uninjured."

That definitely sounds like it should be taking a backseat to, you know, healing. Like what your role says.
