Blademaster devotion points?

[Insubordination]

I have the lion, harpy, assassin's blade and assassin completed. I'd like to get to Blade of Nadaan and Unknown soldier and the ones i'd have to complete to get to those just aren't appealing.

check out falcon for sure and maybe consider throne for some more ascendant. Dire Bear and Bull also work with ascendant builds and you could splash primordial with viper for the %OA boost and vitality resist to qualify for bear and bull. Crane is a good source of order but you should be fine with blade, blades, and lion. Ascendant is really the key.
