Yeah, starting with no MP is a pain, and I shudder to think what it will do to Last Breath, Rockseal, and the Ultimas. On the other hand, the regen rate of 10 per turn instead of FFTA's 5 per turn means that faster classes will regen more and might be more use in longer fights. I can keep my Assassins invisible and just have them wait to regen their MP until they are ready to strike.
