A champ with 4 forms. Potentially 12 abilities.
Looking at Warwick and galio it looks like Riot is starting to make more abilities be triggered by holding the key down instead of tapping it. So I was thinking about what they could do about it and then i thought of this: What if they make a champ able to switch forms by holding it and tapping? With that you could switch between at least 4 forms.
Forms A1, A2, B1, and B2
The numbers are changed when tapping R, while the letters are swapped when holding R.
Ex: You are in A2, and hold R. now you are in B2. you then Tap R and are in B1.
