Hey!
You know what'd be cool and really help players have fun in this game? A guild arena. It wouldn't be simple to make but wouldn't comparatively take as much effort as a lot of the features you're developing. You could have an opt-in to a tournament style arena, where players could put in a set amount of gear or gold or crystals and compete internally for the win! You wouldn't need to bother with coding matchmaking algorithms or reward tiers. Most complicated thing would probably be the "pot". It would probably function a lot like donations - a limited amount so you don't risk revenue, of course
