No. 3 Kassadin
Kassadin has the Rift Walk ultimate ability, which enables him to have insane mobility. He is good at bursting down enemies all over the map as a result, as Rift Walk can have intense damaging effects as well the longer it’s chained together. Kassadin also has the power to silence you, and Force Pulse you. So he can disable you with a blink. Nevertheless, he remains weaker than others, as long as he doesn’t get fed. An OP character in more skilled hands.
