Tell me, what is the difference between moving into a district for the sole purpose of sport or just using a relatives address? Seems pretty silly to say the former has more integrity then the latter. The forma just had a better option.
There is no way to stop a family from relocating into a district so why bother with the other smoke and mirror rules that are in place. Open the borders and let the families choose where they want their kids to go. But then that would take away from about half of the posts on this board.
