POTG is broken and needs to be fixed

I know its not really a bug but still it needs to be fixed. when ever i play either one of my team mates or myself get a triple kill or some other crazy kill but the POTG goes to some guy with 0 or 1 kill. Also I’ve noticed that you dont get POTG when you get 3 kills with your ult unless you get 6 kills with it. I just think its unfair to people who get a big kill streak and people with actual skill. Update: i just got a triple kill as mercy but a ana with 0 kills got POTG.
