2 boxing is ok for just leveling a couple toons, But i think 5 boxing provides so much more. You can farm heroics and badges by yourself, you can run whatever dungeon whenever you want, all the drops are yours!! Lots of enchant mats lol. Plus the gold from dailys! I can't wait to get my first team to 80, But i'm about to start over on Magtheridon to join the other horde boxers!
