Lack of mm in aram

I have leaver status. Tried to get victory in aram. How *** i am supposed to win with people that ignoring tank pick, picking non any 1 quest on tass and nova *** with her aoe shot or smth but high deaths and no damage? Was waiting game for 10 minutes and got people with ~100 profile level and already tried ranked and got their gold or lower. And probably all 4 reported me because nova urged to do it because i complained that we have no tank and asked people why they didnt pick it. Ofc then they picked wrong against enemy set up talents. But tank was supposed to cover those mistakes. And I CAN’T AFK. HAVE TO LOSE UNTIL THE END. It’s not like i gave up in the beginning. I waited needed talents and watched what enemy can do. Still lost.
