[@Prince of Seraphs] Why have the wall in the arena?

You should get into the faction if you punch a hole in the wall yourself, without your power, because that's how you're going to be most of the time in the center - powerless.

Have you ever punched a concrete wall? Take it from someone who has, the wall wins every time. It does a lot more damage to your fist than you could ever do to it.
