Sorry for double post, apparently I can't edit my comment. Can users modify the values in the mod files, for those who don't want it quite so long?

I think it's more insane that there isn't a setting to change these amounts (even if it's just a simply multiplayer) in vanilla. This isn't actually useful for me since I play in single player, and I struggle getting barbarians to spawn when I want them to even without these, but would still be nice to see an option for it in game. I'll remember this mod for if I ever make a server.
