seperate damage and mob spawning rates in difficulty

peaceful difficulty is meant to be peaceful. you have no mobs to worry about and no hunger. but you also have to go very far out to find the resources that mobs normally drop, with some resources (like blaze rods) are impossible to find!

but when you switch to easy mode, mobs spawn too much that it isn't peaceful anymore!

if there was a way to have low mob spawning or alternate ways to obtain the same resources, it would make things a lot easier
