Unlike 95% of the LoL players, I don't aim to be Challenger by the end of the season, and I gave up on trying to be "good" long ago. I'm playing to have fun, and I cannot, for the life of me, understand people who actually get annoyed over the game.
The last match I played yesterday, I was top as Vlad against Cho, raped him to 3-0, had over a 100 more farm than him, roamed to bot (tp) and helped them out a few times, and what does our mid do in the meantime? He feeds their jungler, Rengar, 18 kills. The guy had bloody 407 AD before the 25 minute mark. I absolutely ate the top lane, supported bot as much as I could, but not even the gods could win that game. It was simply lost, as it took 3 of my teammates to kill him, let alone win a 5v5. I ended up with the most damage done and the most farm in the match, but who cares, I had fun.
