This is why more wards won't solve the issue. Players need to be limited to one house per account.

Alternatively, I keep kicking around the idea that all the wards should be player housing and that the FC's should get 'special' housing that is basically an instanced version. Think of the Sky Pirate base during the Mhach quests- an FC could get a house that's basically a base awarded to them by their Grand Company in any number of locations for the sake of 'peacekeeping' activities in that region. Every FC gets a house/base (customization just like the houses) that are unique to the area they choose, and houses open up to the masses.

If we're to have to compete between FC houses that serve a utility to a larger population, why not make it so that every FC (for a price and once a certain rank is hit), gets one without question or argument?
