You shouldn't judge what people pick beforehand, flame them only if they do feed, at this point you should know the game is over. Otherwise hold yourself back, flaming won't help anybody lol.
Still don't like the idea of how much elo determines your skill. I main jungle and when I get a kill top and at this time our bot lane dies, then I gank bot and top dies, does that make me a bad jungler, can I be even blamed for anything in such a game? I could send you replays of my drop from 1.9k to 1.7k, you would laugh yourself your asses off by seeing my teams. I sure did a few mistakes, but even when I play at my best, as a tanky jungler you HAVE to rely on your team, you won't be able to kill enemies yourself or anything. It's just bad luck at some points. Even more I can imagine that being in the "elo hell", or for you people that low elo, since you find leavers in 80% of those games. I only started there, got out of the 1200+ very fast and was lucky, even tho on the way I had tons of leavers.
