Could we do that? (otherwise I don't see how we could really put mobs in mainworld) Also, how about instead of mobs in mainworld, how about better spawn rate for mobs in aether? Maybe make all mobs in mining world hostile mobs? I've always wanted to make an animal ranch/farm kind of like what you would see in 'Harvest Moon' Maybe some type of system where you can /lock an animal to claim it and then they only follow you and can only be killed by you (would have to figure out complications with /butcher) By adding rules about not having huge number of these types of mobs (limiting them to a set number) then maybe the lag could be controled. Maybe put a max cap on the number of mobs able to be on the server at any time. And for non protected mobs, put a despawn time in or something.
