alright here’s my take on what should be added-
MORE VAULTS:
this one is the most overdue, since the ability to drop items was removed many players including notable staff have run out of space and need to bring alts in JUST to hold more items, this should not be an issue so i would say match it to the number of plots each rank gives you
PLOT REVIEWS:
now this one is a little bit of a stretch but i see many lesser known players asking for people to test there map before submission, a cool way to encourage this is giving donators the ability to write there own reviews of plots or maps in a special book and send it to the player (like a streamlined /mail)
ILLEGAL BLOCKS:
as some newer maps are using wackier blocks and concepts there are some that currently can’t be used such as the hopper or the end portal with an eye in it, these are used in maps anyway as shinx just /gives players them so why not use it as an incentive to spice up maps.
CUSTOM HEADS IN PARKOUR WORLD:
currently the /hdb command is map maker world only... why? A great donator incentive is giving players cosmetics to play with and the hat shop is something in big need of updating? Maybe for ELITE only?
SEASONAL DONATOR TAGS:
whenever an event or crate is released a slew of tags are released, usually 2. But what if there was a 3rd one, voted on by donators for each seasonal event to give more incentive to buy titles they helped vote for.
HINDRANCES:
more so a side challenge for those who have done it all, donator only as it seems fitting. when selecting a map for normal or challenge you could be able to select certain modifiers to make your experience harder but worth more mana/score, whether it be nausea or set fov or infinite poison damage this would be a cool bonus for people wanting a challenge.
RACING HOUSE:
a more recent addition to the gamemode is the auction house, somewhere to buy items for mana, but what if by using a /rh or /racehouse command you could have a seperate gui showing currently ongoing races and choose how much mana to bet on the winner, sort of like a coin flip with value, like races themselves you can only bet what you have so it turns into a risk or reward out of your control.
that’s all i have for now, hope some of these are added :)
