Martial arts are not available to some ATs despite the AT possessing something that would indicate a martial arts theme on some level. In other words, one cannot play as a martial arts mastermind, and playing as a ninja mastermind only gives you bow and arrow attacks. You cannot wield a ninja sword, you cannot use martial arts. Since this is a limitation of the set, adding an option outside the primary and secondary options to give a little more appropriate depth seems like an easy fix. Perhaps a better option would be a Martial Mastery ancillary pool for masterminds, but wouldn't it be simpler to add two alternate animation effects to the fighting pool than to create a new pool just for MMs?
