For people saying they are not in the elo they belong try 3v3. You have much more impact.

In a 3v3 you have 33% of the influence on the game, 33%/20%=1.65 -> that's 65% more influence than you have in the summoners rift! If you are good you will climb extremely fast, if you are bad you will decline very fast.

Some of you might say you need to play specific champions, but that's not true either. The only think that is considered weak in high elo are maybe squishy supports (except Lulu) and Assassins. Everything else is played and there are even some Challenger playing off-meta Champions like Shaco Support, Bard or Fiddle.

So if you like to carry your team and win and are ready to take a bigger responsibility for your game head to the Twisted Treeline.
