Dead from Plot hunting and I ask YOU a Question

[ItMe]

They have more houses than you can imagine. It's their business to know these things.

Wow, you're right.
If they have loads of houses, it kind of calls their whole idea into question.
Thet they have bought loads of houses shows how much buying power players can get. Thus in order to for their Gil sink idea to be effective, house prices would need to be prohibitively high.

I know that they aren't alone in this. There are many other individuals who basically own every house in multiple wards.
Instead of making more houses available, wouldn't it be better to simply limit the number of houses someone could own? (Counting houses account wide so someone couldn't just own a load of houses across their alts)
