I am wondering if you can limit the number of claims a player has per dimension, or make it so claims in one dimension (like the nether, it is 8x smaller) weight more than claims in another. Thought is if you limit the world border, the overworld would be quite large but the nether not. You’d be able to have larger claims in the overworld than nether to prevent people from claiming half the nether.

No, but I should probably add something for this.
