This is why Blue Kayn is too strong
If this doesn't make you scratch your head and think "yeah this probably shouldn't be in the game...." then idk what will.
EDIT: Thanks for all the comments. And I've turned into a Kayn mid main and forgot how to actually play league because this is so easy.
For everyone commenting that i was fed. I was the Kayn in this video. I was pretty fed, but not too far ahead. Our team was behind by a lot. I have posted pics to give you the layout of the game when the play happened. As well as the post game scoreboard.

Their K6 is 16-5 and there is no way a K6 could do this to your team. The point is that other Assassins are mostly single target. With the exception of maybe Zed, but even his Q does reduced damage to multiple targets. I've been one shot by many champions when they are ahead. But the entire team shouldn't disappear. Even Kat has to get a good ult channel off and some resets to pull this off.
