Hard to define "worth".
Zhu Yuan, Qingyi, Nicole is my 2nd team (and Zhu's best team)

I love her. She had the best trailer in the game so far and her combat animations are just great. The fact that she builds her weapon while fighting is just awesome.

She clears stuff.
But I'm sure she'll be another Soldier 11 in 3-4 patches... maybe.
No where close to Miyabi, far above Soldier 11 though.
