I don't get the OP's idea.

We currently have a system where a house is relinquished after 45 days and your rent is "paid" by literally opening the front door.

Why does this need to be over-complicated by using Gil or worse yet, using that terrible idea of having to go buy a token every two weeks?

Funny story: I bought my personal house to spite someone just like some of the entitled players in this thread. They sent me abusive tells and saw it as an attack that I was camping the zone for their plot. The thing was that I was actually sat half afk by the market board just outside my FC house at the time.

I like to think of it as a trophy.
