I play on the skyblock server on snapcraft and i realize there isn't many things you can exp for, yes you can enchant in an enchanting table but you can also just buy the enchants in /shop and use a anvil. Maybe a new use for exp could be /enchanter where you can use exp to get books like common books, uncommon books, rare books, and legendary books that all cost more exp like a common book is 5k exp uncommon 10k exp so on and so forth. For example a common book can give you a common enchant for swords, axes, armor, ect. i know that the token system exist but its 100 levels for 500 tokens and there's not a lot of enchants with the tokens for armor. I think with a system like /enchanter it could get more people on the server that like Player Vs Player but don't want to be able to be raided like on factions.
