Did anyone else not yet have the skill mastery necessary to move up to advanced classes at level 20? Wondering if I spread my lessons too thin or what. Even my best units aren't ready yet, sitting at B rank when they need to be at A.
Yeah, you should probably be focusing on the ones you need for advanced/master ranks, but also you can roll the dice on less than 100%. I've had characters succeed at like 39% and fail at 90% so... *shrug*
