That rely on other champions for their power. Im not saying that these new champs will be op, or garbage or whatever, but they are going to be really difficult to balance around. They'll never be good in competitive because one will always be banned out. If they are good, that means that they would have been significantly over buffed to the point where their numbers are so ridiculous that they are broken anyhow. You see what I mean? They either have to be overbuffed or overnerfed since they are reliant on being with another champion that can easily be banned. Also, by reliant, i dont mean unplayable without, I mean not being able to be played to their fullest capabilities.
