It'd be kind of cool if the game has some more in game resources instead of having to rely on third party stuff. Seems like an easy fix to this is to just have them spawn on a timer every x hours, GW2 does this (or the pre-requisites are obvious and there's a spawn delay after completing them) and you can just open the timers by typing /wiki et.

As of now they're kind of a pain to do casually.
