While I'm no expert on this topic, nor am I suggesting riots decisions on yummi so far are ill advised, but I believe someone is going to make a revolutionary discovery about yummi. Someone's going to find an unentended way to play yummi that could make her potentially more of a terror than reworked akali was. I'm sure pro teams and others have already begun experiments with her. I'm excited to see the crazy strategies with her.
Side note: correct me if I'm wrong but if yummi gives the champion she's attached too part of her ad/AP to the champ she's on, could ad yummi be viable? , Alright I was misunderstanding the way that ability worked, I am now a wiser man
