The ability to scale the size of pretty much every piece of furniture would be lovely. I know a handful of other MMO's with player housing allow for that.

I question the decision to release such large furnishings in the first place when only a handful of people have access to a house in the first place, let alone one of ample size.

I'm passing on them myself, though. They're not the sort of aesthetics I'd go for when decorating.
