Did you realize that Doomfists head hit box is completely buggy?

Hey ^^
I am a Hanzo main and I am not a hardcore pro gamer but I try to get one. I am not a noob btw and my aim is also very clear.
Overwatch have manyproblems but my only problem is f****** Doomfists hitbox for his head. Its just me or is his head really really hard to hit?
I also searched in the bug forum of Blizzard but nobodyreported this problem there. I just hate it becouse every time if I try to one shot him I only hit his "body" BUT I can clearly see that my crosshair is/ was on his head and my arrow flew into his head lol.

I just dont get it and its sobrutally annoying.
