Warping is basically never going to happen here as far as I can see. As higbey said, it'd be unfair for hide-n-seek and cause lag. Now, even though warping would never happen, maybe flying could. Get an item that allows flight and as you rise it would begin to show the map in a more broad view so that you could see where exactly you are going. Along with that there could be an accessable "floating island (which is probably already in a pc server)" that would be exclusive to those with this new item.

I need to stop. I am getting carried away with ideas that will not be possible for another few years of Graal existing on iPhones.
