As somone who played Azure Fang since forever, I suggest you still go for that Ao then stop once you get him. Though your current lineup is good as it is already, having Ao will open many possibilities for you. You can't win every fight with raw power alone. That's why I prefer playing with both Mei + Ao since they make decent control teams. Right now I play Sage Naruto, Mei and Ao + AF, and I can pretty much counter that team of yours even if you have higher initiative than me (if I don't panic and use my skills correctly ;P )

Can't comment on Han and Roshi though. I'm still in the dark myself :dizzy:
