So I played the draft pick and was first pick so I called and picked mid. Fifth pick insisted that he will go mid. After I refused to let him, his friends started to threaten me to go 5 mid and report me after game which I was fine with because I never feed the trolls and have enough time to waste their time. In the end they dodged, however :) I`ve attached two pictures here and two more on imgur (names are deleted):
I know that I acted stubborn, but I just can`t stand when premades act like this and think they can get away with these things and abuse solo players only because they have the advantage in numbers. So I always try to teach them a lesson (waste their time).
