Some people are just not mentally capable of playing a competitive game. I just had a Ziggs getting dumpstered by a Soraka. I gave him blue, I ganked a ton, but he was low all the time, he gave her blue buff, and he expected me to come in and kill her before she got away or Kha showed up without any help. Then, he sits in the fountain and just cries, for literally 20 minutes. Twenty minutes of doing nothing. Just sitting there. Crying. Because he got his ass kicked. 1 on 1. With no help, and me ganking like 4 times.
He's fucking Ziggs. He can sit behind his turret and get literally every single creep with blue buff. What the hell?
And it happens again in my third series game. We have a varus. He has a Karma support. She dies a lot. He completely quits. Just sits in base and cries. Both series games lost to whiny little children.
