I'd like a Rage section of the boards

My last game went like this. our midlaner only wanted to play Yasuo mid and picked Lee Sin because he assumed the jungler was going to switch with him. Legit picked Lee Sin, said "switch jungle with me." He then flamed our ADC. Cho' Gath support which was great having a Cho' Gath who can't do anything in lane or out of it. Our ADC picked Vayne despite never playing vayne before and being terrible at ADC. Our Jungler was really chill and I enjoyed playing with him. I just want to bitch about them in a proper section.
