Nightstalker is fantastic with 1 handers due to Archery's 10% CC. If you have a lot of CC up front, it will be going off a lot more. For me, I am getting about 1 Discipline every second back from my skills with 58+%CC. If you can tank, Shuriken storm is also not a bad way of also padding your ability to get a decent return of Discipline when mobs surround you at higher MPs.
