Full attack bonus is nothing. It helps you in no way at all. At. All.
At least, in comparison to a sane maneuver recovery system; hell, the way this is set up, your access to all disciplines is not very useful, since you are still limited by which Disciplines you have maneuvers known from.
After all, even if you had access to all maneuvers, you probably still wouldn't focus on more than maybe 4, in all.
