I completely agree with your list Remedi. Those points would be a very good start. On top of that some more points:

- Ingame and forum surveys about new content.
- Have mods come into topics that are long and/or have lots of likes and discussions going on and at least give us a hint that they read them and will give the feedback to the devs. This way it feels at least like we are heard even if nothing comes from it.

Those are imo quite a few good steps in the right direction.
