I only recently played him fully. What a blast. I love twin stance, and have 1 point in all stance. I play multi bar to switch stance, going from very tanky (100 stack sentinel easy) with crane+dragon, or very bursty (20 sec and less on small dummy ttk) with leopard + tiger, and going serpent + tiger during ultimate, using same omega and same gear.
I don't think this will survive the power update. Hope he will be even nicer, but it will be hard to top for sure.
