Dragon is really only good as a defensive typing as offensively you would need to be using it as STAB or use utility like Dragon Tail or Dragon Scales.
Bug having U-turn alone makes it above D.
Also Dark should be S rank when Knock Off is one of the best moves in the game and also has Sucker Punch.
