When this game came out they didn't expect so many players (even at the beginning with long queues and a very limited space for only 5000 players or something in each world).
So if they created the wards with only FCs in mind, I think they should just go for that. All plots for FCs only. One for each FC and nothing else. No more personal houses...
Besides, we all have access to the Inn's room, right? Is it possible to somehow make it customizable? (instanced, but allowing only 1 char - you, in this case). If that were the case, we would not need apartments and we would only have the FC house to receive our friends making the place even more interesting... (in this way, instead of an inn room, we receive a small "apartment" at the inn, see?). oh, and we could get rid of rooms inside the FC's house as well, in order to make way for more wards (for more FCs to come).
Am I making any sense or is this all junk in my mind and I have to shut up about it 'cause this wont solve nothing? '-'
