People who ? ping when players miss skills or make bad plays.
You know who you are.
We all see you making awful plays and/or missing skill shots.
If everyone pinged your bad plays and/or missed skill shots, you'd have bleeding ears, but we don't.
Why? Because we're trying to be supportive and cooperative. Rather than discourage you, we encourage you to stay engaged and be a part of team fights and practice observing which situations are good and which are bad and keep practicing your skill shots.
When you ping ? to harass your teammates, you're being toxic. Even if it's not chat toxic, you're still being toxic to your teammates. You're trying to tilt them. Why are you trying to mess with your teamwork? Why are you trying to make your team lose?
Sure you may feel better when you lose because you can throw all the blame on one person instead of looking at your own behavior and performance, but it's a self defeating and self fulfilling prophecy. You ping the player because they messed up and you're tilted, then you tilt your teammate, and then your team loses because you've tilted and you tilted another teammate.
So, rather than go down that downward spiral, how about you work on being a better person and encourage teamwork and cooperation?
