User blog comment:MwGirl/My Top 5 worst Cookie ( Based of my Opinion )/@comment-25889587-20160321072543

I mostly agree with your list. However, for 2, 3, 4, they are justified by their ranks though. A and B are not as powerful as S grade.

However, I agree with Ninja Cookie being graded too high for an S-grade. Maybe A would be more fitting.
