Absolutely agree that purchasing a plot is way too difficult.
For a more fun suggestion (that's probably already come up), a way to have a minion in your home would be a lot of fun. Maybe have an interactive "pet bed" that you can assign one of your minions to. That minion would then be summoned in your house and treat the "pet bed" like the player-- wandering around it, doing it's animations. Just a fun way to do more with a minion, I think
