Hi! Thanks for the note.
You're mistaken, though. "People owning wards" is what I quoted, and the two paragraphs that follow break down each of the two issues. That is two separate issues that you are collapsing into one. Issue 1 is your perception that 8 players are one player, they aren't. Issue 2 is how many houses an account can hold.
edit: went back and numbered them, for your ease-of-use
