Which Dragon type & Dragon family member are you most disappointed in?
Concerning the Dragon type, I'd say Druddigon. It's kind of useless to my mind. Ok, I don't like its design at all, so that helps me not to like it but I have to say that I'm particularly disappointed in the fact that it hasn't any evolution. Dragon types need evolution. It's one of their feature, to start with a weak and cute little Pokémon difficult to train but then begin badass and powerful creatures that can easily kick the best Pokémon !
Regarding the Dragon family members, I'm disappointed in Scrafty. It annoys me to such an extent... I can't stand it. I won't start to comment its design, I could become wicked. It's also pretty weak, although its type combination is pretty interesting.
