Most flexible champion and are flexible champions OK? (Can go AP/AD/Tank etc)

Hey there, Onwodori here.

With the advent of a GORGEOUS new Kennen skin coming, I have dusted off the old ninja and returned to work. Got an S+ support game with him and I remembered --

He's a ludicrously flexible champion. He has AP scaling for the most part, sure, but is capable of being a legitimate ADC. What's more, though I don't know anyone else to use this, he is a fantastic engage tank / bruiser, with massive movespeed and up to 50 free armor and MR with his E. He even has consistent, strong CC.

Basically, I feel like he *can do anything, though is the best at nothing. Are champions like that OK to exist in league, or do you think Riot will come along and give them more of an identity, as they have been doing with many, many champions of late (Marksmen COUGH) ?

So my vote is obviously for Kennen. Who is your surprise flex pick? He works in just about all roles.

Thanks,
