This feeder just messed up my game

I've removed the images you included because they violate our Boards policy of no naming and shaming, including reporting other players on the Boards. The Boards is a place for discussion, and not for escalating reports against other players. If someone is trolling your game, please utilize the post-match reporting feature; instant feedback gathers data across matches to punish players like these. You can read more about the Instant Feedback System on the Instant Feedback System FAQ.

Report him after the game and the system will do its thing.

I know it's frustrating to encounter these players, but the system is pretty good about hitting them with penalties. This board, however, is not the place to report people -- there's specifically a policy against naming players, so it would be best to take those images down before the Moderator has to remove them and/or lock the thread.

was it ranked?

According to higher ello players you just need to "git gud" and carry the team.
