Denying Pentakills
Denying a pentakill for the enemy team is completely understandable. However if you steal a free penta kill, let's say you got a quadra kill and the last enemy alive is low health and it's clear to everyone on your team that it is an easily secured penta, you are a SCUMBAG.
I understand some pentakills can't be secured because your team just instantly deletes everybody on the other team leaving you with only a quadra.
But really!? I had two quads in the same game both denied by the same person. The reason being: "Pentas aren't cool. Go play hexakill if you want pentas"
Like wtf dude. Ofc blocked, reported. Even players on the enemy team were calling him a scumbag. What happened next: I tilted and threw the game :D
ALSO not to mention that this person trolled as Elise top lane with an astounding 20% kill contribution and had the worst build NA.
