I was thinking.... the Lounge is pretty underutilized atm in my opinion. The FM far outstrips the Lounge in terms of functionality so nobody ever uses the lounge despite the lounge being more accessible. Maybe there are bigger priorities like autoban... But, what if the Lounge could implement instance based player housing? Idk how it is to code but what if players could have instanced versions of their houses that they can customize. Could also be a mesos sink? idk. That would be a really cool feature though. Or maybe guild hqs? If this is too hard to code (though imo really cool), maybe the Lounge could be outfitted in other cool ways to have more functionality!
We have some plans for the Lounge in the upcoming patch. However it's not something you mentioned. And probably not feasible / possible.
