New Champion Concept (Ditto)

You know the Pokemon Ditto how it shape shifts? Well I have a similar but much cooler idea for a new LOL champion. The concept is that this new champion is a random but very varied one, which make him very OP (Pro) but very difficult to use (Con). This champion will be able (except Ult) to shape shift depending on what other champions are in the same match.

**Q, W, E : **These will allow the champion to shape shift to another champion at his will. The available champions to change to are balanced as much as possible (but yet random). So let's say Janna, Eve, Ahri, Jinx, Caitlyn, and this champion are playing in a match. The possible champions to shape shift to will be Janna, Eve, and Jinx for instance because each of them is of different kind (Support, Jungle, ADC respectively).

R: This ability doesn't shape shift this champion, but shows him for what he really is, an uncontrollable monster. When the summoner uses the Ult, the champion is incredibly buffed/ powered and goes into rage attacking a random champion in the Ult's radius leaving that champion either dead or very severely injured. The pro is that the ult is very powerful (above average) but it's very random (especially in team fights).

Passive: Because of this champion's shape shifting aspect summoners won't know what spells to buy for it (Support? Tank? AD? Jungle? etc.), so the passive will help smooth out the problem. What the passive does is take a specific percentage (maybe 7%?) of the summoners highest stat and adds it to the other stats. For example, if the summoner has 100 damage, 7 is added to the summoners Ability Power, HP, Mana, Mana regeneration, Attack Speed, magic resits, etc.

*I know that Riot has recently been trying to come up with unique concepts for their champions so that no two champions would be the same, and I think this is just the perfect new champion concept. *
