Aaaawwww come on, you mean to tell me Pein is so strong he can kill Kakashi with a simple nail? This is bs, who's writing this stuff now?
Well, they did skip a lot of scenes in between.
Notice one page, they are all "we can do it!" and Pien has a chidori inches away from him. and then the next, they are all on their backs in pain, with Kakashi stuck under a building?
There was a time difference in there where they all got their asses kicked.
By the way, who else besides me wanted to see some Ino-Shika-Cho Sr. action here?
