Please stop feeding in norms
The title says it all. Stop using norms as an excuse because you fed the other team. Just had a 0-11 Draven on my team. No matter the game mode, you should always try your best and try to win. I play League of Legends because it is fun and I enjoy it, but I also play to win. Ending up on a team with someone who doesn't try ruins the experience for everyone.
