They should just make custom built EA houses for the winners, give you a selection and you have to choose from one of them.
I personally would much rather have that. It is suppose to be an "Outpost" for the forces of the humans/gargoyles to stage from right?
I personally would hate for someone to win and then put a green plot with no house in the Abyss, and it just stays like that. Similar to how some luna houses are just barren plots...
