Ok, well, I'm a little confused as to what you're complaining about.
I haven't read the new Iron Fist yet, so I can't totally speak to what happened, but I know he was replaced. I'm guessing eventually the status quo will return
I didn't say it was a good fight. I read it and I thought it was unbalanced too, although maybe Blackheart was weakened by fighting so much. Anyway, my point is, why blame diversity for that?
