I understand what you are saying but i'm not worried. I think the game is heading in a good direction. I think future reviews will still be harsh though just for the simple fact this isn't WoW. It's always going to be unique and is never going to have the sort of mass appeal a game like WoW does, but there will always be an audience for FF XIV and it will survive.

FF XI never got amazing reviews and it's lasted 9 years and will most likely last at least another 2 to 3.
