Worst POTG has got to be when some guy on defence kills a bunch of attackers that are rushing the payload as the clock runs out. I get that it's a lot of kills very quickly, but there surely has a be a better play than that.
Also when a Reaper gets POTG for death blossom, but in reality during the game, a Mercy immediately reversed all the kills moments later with a Resurrect. I think they should sort of cancel out.
POTG has potential to be great when it does catch an awesome play, but so far, it's just the same thing over and over again.
Agree, it's just multi kills, which are usually incredibly fortunate.
