My entire group is having issues fully completeing the plot instances for chapter 60. We've tried multiple combos, characters, and talents trying to pass the high dificulty section, but get slaughtered every time.

I'm lv. 67, with my ninja's fully cultivated and awakened, yet I can't get full battle points for Scout Deadwood Forest, Shikamaru's Battle, An Evil Secret, or Birth of a New Ninjitsu. The high difficulty section is impossible!

What are we missing?
