Jhin damage is BS

I was with had

I had full health, he shot me 4 times, I had to flash away with a sliver of health left!!!!!

WTF is that damage. I looked over hit kit, it doesn't make sense to me. Can somebody please explain that damage. It's my most recent match played.

I literally could walk into the other 4 members of his team (I actually had 2 unofficial quadrakills, a triple-single and a double-double), but couldn't 1v1 !

I know Darius is a bruiser, but with that built, the only marksman I've ever had a problem with is , not because she does a lot of damage, but because the permaslow makes it impossible to get close. But this guy, literally shot me 4 times and made me change my mind about engaging him.

... then I died to his ult as I was attempting to run away.
