I don't understand why they don't just make all plots Large and let people choose what size house to put on it. Small house, large yard. Medium house, medium yard. Large house, small yard. That way nobody has to move, they may just move for a change of scenery or to be closer to friends.

Now as far as the raiding goes, I totally understand what you're saying. People in my FC have been transferring out just to stay on Primal because of the already established community. I'm going to ride the wave and stay put, but I may move my old main (which is currently on Aether DC) over to another world on either Aether or Primal and just use that specifically for raiding so I don't feel as though I need to keep up with two characters and I can enjoy the content to my hearts content.
