I find myself hunkering down for the night in my cosy wool bed, as to avoid being ravaged by the mobs outside my home. Exp isn't motivation enough to kill mobs, as you can get that simply by smelting. Perhaps there is a mod out there that makes aggro mobs spawn near you if you sleep too many nights in a row, or if you haven't met some sort of bloodlust quota in time...or something along those lines?
I had a request for such mod, which requires the player to kill a certain monster count in a day, and if you failed, you'd be insta-killed. If you want I can upload it here or you can join my discord server and get it there.
