I have heard rumors that a new land is coming out (zorbi?). I have heard hackers hack in and see a new tower. I think that hat tower should have TWO flags. Yes two. They could both have 125 health and it would make tower taking stragtegies different. A little bump of newness to graal.
Totally new topic: I think that there should be an underground to graal. Like a whole new world with catacombs and basements from other buildings and towers. You could enter more secretly. It might be useless but it would still be cool.
