Remind me how you can even play against Viktor?
He has absurd range, one shots people, has irrelevant mana costs, has hard CC, has a shield, can just push R and forget about you as you die, he's half targeted, and all that.
I just don't see how you can beat him, short of fighting outside of his range for the entire game (I can only think of two champs that can do that and still be effective), and never going into teamfights so long as he's up.
