Yeah. Part of the lack of response is caused by the general behavior of community members. Anything related to Mercy is met with extreme toxicity, and this makes it hard to say pretty much anything about her, except for spinning her nerfs in a positive way.
I’m starting to think that the best way to ‘communicate’ with the Mercy community, is to take high level Mercy players like Titanium, EeveeA, etc. and work out something in private conversations, far away from the community forums, possibly with an NDA slapped onto it, until something workable can be presented in the patch notes.
The way I see it, they’d take the highly liked Mercy rework suggestions, such as Why I Have Yet to Not Despise Mercy's Current State or Suggestions for Mercy from someone with too much time on her 📝, get the authors and, like I said, high level Mercy players involved, and run everything through a process of elimination. Take out the things that won’t work, keep the things that do, and try and combine that into something that can last a good while.
