This might be better over in the "Minecraft" forums, rather than in General Discussions.
But I'm wondering why you need more than three homes in the first place. Where are you putting them all? I typically used two - one for my main home in the regular world, and one for my base in the resource world. The third one I figure I'll use if I ever attempt to build a mine in the Nether (but it's scary there, so I've never attempted it.
). So I could see the use of four if someone wanted to build a mine in the End, too. But 10 seems a bit extreme to me.
