as much of a legitimate sport as football or baseball, IMO. You have to be in tip top shape to be competitive, not to mention the skill set you have to develop, both physically, mentally. You have to become a master tactician and have the ability to speak numerous languages, from troll to centaur. I doubt that most CBers would know how or have the skill to defend themselves or their guild from an attack by a level 27 dark wizard or would be able to defeat a Ravenmist Banebattler from the Seventh Sanctum.
