The issue with this question is that it is very, very dependent on the skill level of the group. And it always has been that way in dungeons to a fairly decent extent. If you ask the people at the top that run in organized groups, you may well get a very different answer than if you ask people who PuG with randos. I can heal a +3 and be healing my tush off most of the time, and know full well that this group would absolutely not have finished the dungeon if I wasn’t being awesome, but then the next day I can go a few levels higher and have a group where I’m basically window dressing except for a few moments, and even then if they are good with defensives they’d still probably live without me.
