I would encourage OP to edit the first post and provide the healer issues, as someone pointed out in r/ffxivdiuscission, to quote:

I respect the effort. I doubt it will do anything in game, BUT it can gain a lot of traction through social media to the point where big content creators talk about it, leading to SE having less excuses ignoring it.

The main problem I see with the forum post is that it needs to have explanations for why healer mains are upset, what change they want to see, etc. There was another “summary of healer problems” thread I saw on the forums, they should have a link to that in the OP.
