This is why a bit before the SoD announcement I made a separate post asking for Era to get its own forums. I think it is important to the long term health of Era for the community there to have a dedicated place to have discussions, voice concerns, and show consensus on topics.
(All the responses to that post were basically along the lines of: “these are the official Era forums” - link to post from 20 days ago: Official Era Forums? )
The need for official Era forums was drastically amplified with the announcement of SoD.
I agree that it is possible to mute topics and hostile posters, however I think the forums should generally be welcoming and the last couple weeks have shown it is very hard to do that when two game modes that appeal to very different players are squeezed together in a single place.
If there is a simple fix that can be done to prevent players from facing such hostility - it would seem healthy for blizzard to act upon it sooner than later. Adding another category to the forums is fairly trivial.

Oh how I wish that was still true
