It's actually far from impossible. Maybe I'm just the *casual* here. But so far the dt dungeons heal checks have resulted in a LOT of wipes from either myself the healer deing. Or having nobody to share stack damage with. I think the new dungeon design is doing it ls job tbh and I would not say healers are obsolete in there. Perhaps in the future. But them there will still be the newer dungeons to do where they WONT be usless.
