"Events"

[grave harbor]

I think some sort of event system would be cool, similar to the Present Rush top five leaderboard competition. Maybe one month it's "Most Solo Eggwars Wins", the next it's "Most Skywars kills". I do not think it will remove the casual feel of CubeCraft away from anyone other than the players grinding, and if they're grinding, chances are they do not necessarily want a casual experience anyway. The reward could be something like a prefix or a win effect. 🙂

There could also be no reward other than bragging rights, and I think people would still enjoy it.

This actually is a pretty good idea

I think that's a good idea, but how about you only get the rank or reward for one month and then have to qualify for it again

Not bad
