Fully agree with that last part. If we can limit phantoms to one world (alpha) so players can still use their features, that would be great. As Amnot said, they are more of an annoyance to a lot of players because you can either go below sea level or go sleep and they are gone. It's not hard to do that but it's also not the most ideal, especially if you are using your /back command for something and now you have to reset your positions I guess you could call it. They aren't very difficult, especially with armor on. Just an annoying mob that probably 80% of the server has no use for.
