Can we talk about this? (Tahm Kench/TROLL)

Ok, so, i was waiting for a game, a little buzzed, i was happy, didnt really care what lane i got, i just wanted to have a nice fun game, got into champ select, 3 of the other people were also being nice and friendly, then theres the one. he decided, that after i called top, he was going to autolock TAHM KENCH, with ghost and flash. i said "ok, maybe hes going support, idk i dont really care, i called my lane thats that." well, he followed me up to top lane, so i said what ever, went dont botlane to help our adc, about 2 seconds later theres the fish. he ate me, threw me into the other team then ran with me just to get us both killed, soon after he did the same to our adc, then our midlaner. SO.... WE NEED TO FIX THIS. People shouldnt be able to just troll by picking tahm kench and constantly eating their teammates and getting them killed, and feeding. <Removed by Moderation>
