Because I made them to begin with and I believe they are a mistake I made. The Sonic cast is so diverse in abilities that it is impossible to classify their skills in certain categories. Also, if we are going to classify one set of characters, then we are obligated to classify every character's abilities across SNN, and I dont see that happening any time soon.
I did not forget about Rouge. I just don't have time to correct those headlines now. It takes extensive efforts and research in order to merge certain sections and their contents. If I were to be honest, I just rushed Knuckles' article, and I feel pretty guilty about it. I will take care of it when I have the time.
