"STFU NOOB YOU RUINED MY KDA"

When did this start becoming a thing in league? If you can end the game and your kda is crap do you really need to chase down that last kill or two to do it? If you have a player on your team that has very few kills a couple of deaths and a buttload of assists are you going to hound them on KDA cause you think that makes them bad?

I remember as soon as TF2 went free to play this became a big rant for some players. I understand that dramatically low statlines are detrimental to the game your playing but unless someone is feeding intentionally, K/D/A should not be the reason for flaming at others.
