You should make the GKITS unique on the gamemode because its grind based not pvp based
(you can check here) and you should do something about the rules mostly:
-people had enough of the problems going around with island tops such us merges and all so clarify it once and for all
-about ideas I think you should pay more attention to corps like you did to drugs on prison maybe add an npc that would be called (farmer) on spawn and such things.
- Get /lotto again.
- Try something new or bring something alt such as Blocks value ?
- WORK on balancing the loot prices compared to spawners pricing.
- Make spawners limit per island, and make it so you have to grind island missions and shards in order to unlock more capacity (will encourage more grinding and less afking).
- BUFF Ultra/Rare crates !
- Fix 30%books as they are mostly 0.1%
- Add a new update in /ah where there would be a bidding section where a player puts an item for like an hour and people bid on it and whoever has the bigger bid gets it (once you bid you can't get your cash back).
- iChest shouldn't have taxes nor to be nerfed, its already expensive and doesn't carry over seasons.
If I have more ideas I'll list them below, specially about custom enchants.
