Hey, is it maybe a good idea to add something like 'ranked skywars' where you have mutiple divisions. from iron-gold-lapiz-etc etc etc. Every division you enter the more coins and experience you gain at the end of the season. Hypixel has ''ranked skywars'' aswell you may want to look how it works there, becuase i don't know how to explain it right :S
and good luck!
