Amumu needs a friend.
I think it's time poor Amumu gets a friend. He's been treated so shitty ever since his creation. The idea of party time Amumu is just cruel. Riot has to recompense the loneliness they caused Amumu to feel. Maybe they could create a champ that's all about love and could not be able to NOT love everybody around him/her. The champ could give to much love and (as an ability) hurt champs around him/her by giving to much love (like hugging and pressing someone very strongly). The champ therefore probably doesn't have much friends either but he can be frienda with champs that can't really be hurt by hugging because theire so strong or something. And of course he could be friends with Amumu even if Amumu is cursed. There are so many possibilitys to create a friend for Amumu that it's just cruel and unfair not to do so!
