I know that feel mate. Had a similiar game yesterday where me and my trusty support dominated our lane. Our malph managed to feed the enemy Rengar 6/0 early game and went on to cry about how it was our midlaners and junglers fault for not "helping him enough" when he kept overextending in lane :c..
Game lasted 64-65 mins and was lost when Malphite decided it would be a good idea to push but alone x)
But hey, the game wasn't half bad. At least I learned some new things about Quinn c:
