Welp that was the shittiest game I've ever played

Was playing Kassadin, got fed and was shot calling all game, everything was going good until we had a choice to go for baron or dragon when they had 3 up, except their 3 that were up were all decently fed so I said go for dragon cause they are near baron waiting to steal it... When the whole team meaning 4 of them decided to baron I specifically wrote in chat, ok let's throw, guess what happened?.... Why do people stop listening to the shot caller, he obviously is a good team leader and knows what he's doing.
