Diddy can't use his normals with a banana. he sacrifices his offensive options for super solid defense. makes him adapt to the situation and allows for really creative play.
i always liked diddy for his item manipulation and control with banana. hes my project m main. didnt use diddy at first here cuz i was turned off by how broken and easy he was at first when he could just win with grabbing and up air. the nerfs made him more fair and true to his design. picked him up today but ive been considering it since i watched mvd and zero use him really creatively at CEO. probably the most fun character to watch at top play imo.
