You know what chaps my ass?
When you are ahead and a teammate afks because
A. There was one bad play or B. They personally are doing poorly (or if Braum Poroly) that game
I hate this even more than Afking when behind becasue there is no reason whatsoever you should be upset (The Afker)
I had a game where we wer pushing down mid and a few of us got caught, so our Orianna (Who was approaching her 3 item power spike and only at a KDA of 2/4/2) afked when the rest of us were ahead. FFS were were hitting the Inhibs.
PLease don't be that guy
Another game where we had a fed Rengar, we got caught pushing mid, and even though he was carrying us, he AFKed.
I understand that tilt is a thing, but you can at least pretend it doesn't exist before it really gets to you.
