Like the title says, who is the easiest champion to counter? My friend says Eve, because one ward will do it, but I argue that A. You stay away from the ward, or B. You lane switch.
I guess the real question is, is it really that easy to counter Eve (mid-elo), and are there any heroes easier to counter than her?

if your playing teemo or have exhaust you can stop pretty much anyone like yi, jax, tryndamere ect. a cleanse can get you out of warwicks ultimate while it leaves him stunned there for the duration of it. also if ur going against anyone who heals or stacks a lot of lifesteal, ignite (or executioner's calling although its not what it once was) will cut the healing in half making them much easier to kill and once again exhaust will just stop them for hitting you so u cant get hurt and they cant gain any health.
