There is a difference between kicking sand, and say the building, which goes from horizontal to vertical, forcing you to run down it, fight, and avoid the pillars that pop up. 

And this wasn't aimed at anyone, arena ideas tend to pop up that serve more to make the people fight against the Arena, than the opponent. Honestly, I have no real idea what Terminal's Arena's have going for them, haven't seen them(as they aren't posted).
