Start using the polling system more. One way you can do that and combat where information is being discussed instead of your official platform is by using the in-game polls on things mentioned in Reddit/Discord.
Why is this useful?
It would be interesting and more useful to put any suggestions you guys are discussing in Reddit and Discord up on there to see what the community thinks about an update. It would also make use of a system that you guys implemented for this very reason.
How can this work, potentially?
The in-game polls are very rarely used and that is very disappointing considering it's potential. You may need to even rework the polling system a little bit to get it working the way you want it. Mention that there is a poll on login or have a splash screen stating that there is a poll (with a toggle of course). Also, take advantage of the tiers system you made for it (ruby, dragonstone, etc etc). It obviously is not going to get much traction until you start using it for about a year instead of putting things on Reddit or Discord, but eventually, people will realize where they can go to vote on ideas. Suggestions can still be made on both other platforms, but the real decisions/feedback can move to the polls where they are meant to be, not from the minority that sees your discussions on Discord or threads on Reddit.
This puts the power back to all active players of the community rather than just a few hardcore members of the community that roam the Discord chats/Reddit discussions at the right times. It would also hopefully avoid misinformation given to the community from players or JMods alike. JMods should only be able to discuss what has already been discussed, and I am sure they are tired of dealing with the blowback of the community when something isn't done the way discord discussions went.
