Suggestion: double round-robin

[VesaSeppänen]

Would it be nice if there was an option especially in the Arena format where when you play with power A against an opponent with power B, then a second game would be played reversed with you having power B and the opponent would have power A? I'm not sure, but this method may be called a "double round-robin". I suppose this would be like in some chess formats, where you play with white and black pieces equal ammount of times.
