I do agree that it's the devs job to fix healers, which is why I like to put my complaints as more like... vibes. I may post my preferences, but I'm more interested in the vibes.

1) Needing a healer in 99% of content feels like a skill issue, that is, being a good healer is wasted on a good party.
2) Healing good is boring in a good party, that is, healer engagement is way too dependent on the party playing poorly in respect to the content they are in.

Now, it is possible that someone likes these vibes, or rather, that they wouldn't like the vibes if my issues were addressed, but it's much easier to see conflicts here rather than get caught up in the details.

(Though I do enjoy doing some kit theorecraft myself, haha)
