If there are too many dungeons then it starts to ruin the economy like how it did when on WOA the custom dungeons were first added and there was one every few hundred blocks.
I have a suggestion that I’m not sure that is already implemented. How bout people with ranks get more claim blocks per hour, but every rank is different. For example Expert could get like 300 claim blocks per hour, Master could get 350 claim blocks per hour, and so on. That could increase the interest of buying a rank. Or you could just do a singular thing that you buy for like $5 that permanently doubles the amount of claim blocks you earn per hour if you don’t want to spend that much money on a rank.
