1 make it so u can buy cubelets in the ingame store for maby 500 points or 1000 points.
I think cublets should remain as something you earn not buy, whether it would be with real or ingame money my answer is no,
cublets should remain as something you earn to encourage players to play more games and try their best
if it was by vanity points you will see players having so many cublets because of how easy it is to gain them
2 and that u get 100 vanity point a day for no ranked people or that u can get like 50 vanity points for a easy or hard daily challenge.
i like the way you think about the challenges but i think vanity should remain for donaters, the EULA has done enough to donaters we should let them keep this
(EULA: A rule mojang [owners of minecraft] made that no server is allowed to give donaters any advantages in any game but cosmetics are allowed since they don't impact gameplay)
3 and i have an other idea make a new glass cage for skywars make a rainbow cage thats awsome.
This should not only be available in skywars, make it so that all games can get the rainbow cage, but it is the coolest cage and i don't think it should be easy to gain
