I think it isn't a good reason to say that because Mewtwo wasn't that good in competitive play. Jigglypuff also wasn't the best in Brawl, but it didn't stop her from returning. They can easily fix Mewtwo, he is still a cool and popular Pokémon. And besides that, he is the strongest Pokémon in the universe (when he has his mega evolution on)
