I had that same thought actually, although for RL utility it's hard to beat Sleeping Goddess. That's actually an interesting sub question though: How would you rank the disciplines in terms of usefulness if you could take them here?
I think I would pick Sleeping Goddess, Radiant Dawn, and Chimera Soul as my top 3 picks, covering mind reading and teleporting, Healing and utility, and Shapeshifting madness.
I mean, Radiant Dawn has a 5th level stance that can let you create a ramp anywhere....
