I was just in a ranked game where I was second-last pick. Jungle and ADC were open, I wanted to jungle, but last-pick said they didn't want to play ADC.
So I decide to help out the team by going bot, and took Mordekaiser.
My Thresh support decides I must be trolling so he takes heal and starts building AD, takes most of the minions, flames me for taking "his" last-hits, then leaves me alone in a 1v2 lane after level 3 or so. He goes roaming, but leaves me with a Relic Shield and a W skill that I can't use.
I try my best, but can't do very much in this situation. Still get a few kills and don't die more than the others on my team. We lose, of course, and both the support and jungle want to report me for trolling.
Amusingly enough, the enemy team were saying in /all that we probably would have won if Thresh hadn't left me alone for the entire game.
So, yeah, that was fun.
I think I should wait a few weeks before trying that again.
