I had actually brought up the idea with my fellowship of suggesting wilds mats drop from world bosses to keep them somewhat relevant, such as Elongata, and even after you’ve gotten rings/capes from them. As seen in many other pancake mmo’s, world bosses typically drop decent gear and loot, which made them desirable to kill even once reaching end-game.
My thoughts would be to have a small % chance to drop 1-2 of a wilds material, and have a slightly increased chance for those drops to be nearby wilds materials (sanyael for example would have a higher chance to drop crowns foil/sour bell than bloodcaps/plains helm/water toad if the material roll was positive). This would keep players in other areas besides shard dungeons or the wilds, and giving a slower but safer PvE route to end-game potions.
