in vanilla theres only 2 methods of obtaining treasure enchants(ones u cant obtain via enchanting so mending and frostwalker) one being fishing and other being dungeon loot... the only method of dungeon loot i know of would be end citys which theres only 2 in the end, they reset once every few days, and the reset exactly the same way soo same loot inside the chests(not sure how because i thought 1.9 changed loot tables to be generated upon opening chests unless they changed that back when they removed luck)
so this leaves us with fishing which is like the most boring thing in vinilla and would be hard/impossible to afk with your fishing changes... so maybe make end citys regen with random seed(and add more/reset more often) or add a PvE method of doing it(maybe a building with randomly geared mobs spawining that can drop thier stuff and can have mending along with having PvP on in there so it can get hectic)

) Perhaps they should add some sort of gambling chest at spawn. If you get on the server called Hypixel, in Skywars they have the "Soul Well," where you pay and it spins and whichever item it lands on you get. (Weather this is an actual item for sky wars or in-game currency) You could perhaps pay with power shards 
A terrain glitch that left a giant crack in the world? (Just guessing)
