How to counter Swain
Since I know a lot of people are going to say he is broken and unbalanced, let me explain how to beat him.
Don't let him stack his passive, he cant use his ultimate if he has no stacks, and the more stacks = more damage.
That means you need to dodge his W (Eye of the Empire) and E(Claw Ability) Both are very predictable.
Without those he is weak, almost sadly so.
You're welcome.
