Why is the healer class basically a one spell dps class?

[Maltothoris]

The devs don't care about healers at all. It's so obvious. I literally just got an email asking me to vote for my favorite Endwalker reveal (from stages to male Viera to the new raids). Sage isn't even an option. Oh, but you can bet Reaper is.

This was relation to the digital fanfest and SAGE was revealed before that. However, the fact they didn’t release a poll after that announcement is kinda telling.
