When will you really address the housing availability problem?

Does that game/developer have to remove other UI elements in order to make TP bars without numbers possible...?

There's a pretty substantial different between "not feasible" and "poorly executed/incompetent".

PS3 limitations

..are not the problem here. The PS3 doesn't care if there are 2 housing districts or 2 million. It's only loading one zone at a time into the PS3's memory, not all of them, so the number is irrelevant. It's why you don't have to upgrade your PS3 every time they add a new dungeon or other adventuring zone to the game.
