Lack of triage and the absurdly high healing potencies play a huge factor into why healers have so little engagement with their actual role. When you can set up at 10k regen tick, it crosses far into ridiculous categories. Likewise, the predictability of fights impacts them both. Nothing can truly be addressed until the devs embrace less scripted, high triage based fight design. I'll go one better and argue tank immunities are also part of the issue. I suspect their intent had been for emergency use, but we don't run content like that. All immunities have become is removing an annoying mechanic from the fight. Unfortunately, I can't say how well received high triage would be, especially at the lower levels. On the one hand, it would go a long way in forcing players to actually improve at their main role. On the other, well, whenever I let my co-healer solo in DF they tend to panic.
