I think this could be saved if you were given the chance to change the maneuver at the end of a long rest. Rangers have a choice of one (out of two) that they can't change. If the fighter could change their signature maneuver every day, that would be really useful. "Oh, were entering the lair of Deathclaw the Lich tomorrow? Lemme specialize in Break Spell."Yes, but do you agree that giving as part of a capstone feature something that another class (that is supposed to be NOT a master of maneuvers), can get at level 9 is seriously underwhelming for the fighter?
I think I'd houserule that in, even if it doesn't get changed.
