I am pretty keen on allowing free manoeuvres on a crit.
So while you can attempt a Disarm Weapon attack, it will be very very hard to pull of. On a crit however, you can choose to automatically Disarm your opponent instead of doing max damage.
That is obviously just the basis and it would need refinement in terms of mechanics, but the general idea is that you do get to do cool things in combat, but you really have to wait for an opening to do so rather than repeatedly trying to spam a manoeuvre.
