It just depends on what all it winds up being. For everyone of you or someone else who thinks it's a waste to just be a buff station, there's one of me who is interested just in customizing one and using it to help me level my additional classes (especially gathering/craftin) easier. If this is in before I've grown tired of the game, it will likely earn them some sub money from me so I can see more of the game.
If all I have waiting is an uphill slog through fate griding with nothing extra to do in sight, I may just quit playing and never pay them again. So, take that with a grain of salt because everything is appealing to someone. Housing is typically appealing to a lot of people who play these sorts of MMOs (RPG focus).
