When you create a tournament you have the option to choose swiss for more balanced pairing. The point with Arena is minimum wait time and fast play.
Not sure an option to play with different pairing rules would work, but maybe Arena could try to balance color for everyone like swiss if it didn't increase the wait-time that much.
