So I'm totally using this in my current game. The party is a group of 5 (Human Factotum, Catfolk Sorcerer, Desert Halfling Rogue, Human Cleric, Goliath Psychic Warrior) and the PsyWar and Sorcerer have both earned one level of Badass. The PsyWar is using his CMA at every opportunity and it's saved his butt on numerous occasions, but I think the Sorcerer has only used it once so far. /shrug

At any rate, the players love it.
