We have over-harvested rare item X. Currently solution is to have global pool of X which throttles the botters but screws over everyone else.
What if instead, when you harvest/forage/collect X it instead marks the area around it with field "X" that prevents new X from spawning there for a time.
This way, botter's cave will eventually will it with X fields while I can casually forage glimmermoss every now and then from my own cave.
Of course problem is that botter would simply mine out massive area for glimmermoss to spawn. Something about that should be come up with. Maybe fields are larger in open space? Well even if no effective fix for this, at least it would make botting require more setup and more importantly, also let more casual players have stuff currently locked behind global pool.
