I would think one of the big things that would have to be tested is the walls and gates HP. How many HP does this gate or wall have, To little HP and what is the point of having walls and gates. To much HP and you will need to hire every tribe in the game to help you knock it down. And that's just one little part of it. I think territory warfare is a long way off.

Think the game has come a very long way, But it still has a long way to go
