Haha, at least getting started on answers. I guess let me be fair and put some of mine.
  • Hire more GM and encourage them to be more proactive in the community
  • Hire more moderators for the forums and have them engaging in chat more often
  • Expand Hall of Novice to include all key mechanics
  • Build/upgrade new servers, perhaps expanding on region and helping to specify so players know which is closer to them for a better connection.
  • Implement the ability to request duels in areas outside of Wolves' Den
  • Remove kupo nut requirements for mobile application and let it have full use, letting players use Market and their inventory from phone...if they want to pay the extra monthly fee
  • Integrate functions in chat, such as letting there be clickable links for Discord
  • Modify New Game+ to include experience and gear. Let the person fully experience the game over without having to make a new character, or at least give the player the option (but gear can't be sold or desynthesized. only purpose of rewards is to continue story in New Game+)
  • Add more options to "Report Player" than just RMT
  • Keep existing housing and system for players who choose it but expand the amount of plots. Then add instanced housing that anyone could buy with no competition. The difference would be instanced housing wouldn't have visible neighbors or the scenery you get in normal plots, but you would have land and an actual house to do with as you please.
  • Make sure all (important/MSQ) cutscenes had voice actors. I'm not sure why they only partially voiced it and left the other half or so with nothing.
  • Remove mentor status from anyone who isn't actually serving as a mentor. (plenty who got the crown but then never help in mentor chat).
  • Add world chat
  • Create some weird and awesome dungeons, raids, and trials. (Like maybe we'd be able to go up against a boss like Ragtime Mouse. One of the mechanics might be where he becomes immune and asks a question. The group has to attack all the wrong adds and leave only the right answer up unharmed. If you fail, you're penalized randomly like maybe his damage will be doubled or you're given status ailments that can't be removed. If you answer correctly, the group gets buffed and he loses immunity).

To be honest, I've got a LOT of other ideas. But I'm falling asleep as I'm writing this, so off to bed I go! I hope to see some really awesome answers added by people. (also still waiting to see how many people say anything about bots or RMT. If that truly is on anyone's radar lol)
