People who get fake penta!
Really grind my gear. It one thing to get a penta by yourself but seeing streamer on Youtube who get penta because their teammate decided to let them have it is just stupid, but the worst part is they are celebrating realizing that their teammate could have gotten the kill instead but ops to let them have that kill.
It like no, you didn't actually get a penta. Your teammate decided to slow or not take the kill to let you have it. It the equivalent of a teammate in basketball not getting rebounds so that said player can get a triple double or break some kind of record. I mean you really didn't deserve it and at most you get a quadra or triple kill.
Of course I would do the same and give my teammate a penta if I can because I would hope they do the same for me but it the principle and the act of celebrating when it not even a real penta. That what really grind my gear.
