The match maker is not the problem. You guys need to stop making these threads.
The problem with the game is that small leads are far too easily turned into large leads that are eventually impossible to overcome. 90% of games are decided within the first 10 to 15 minutes. The match maker has nothing to do with that. Anyone would seem like a Challenger smurf when they are 3000 gold ahead of everyone and it's not that hard for someone to get a lead like that. All it takes is one or two assholes running it down.
Take any Bronze 4 player, put him on a champion like say, Riven, Diana, Jax, Yasuo or Tryndamere. Put him in a Gold 3 game, run into this guy about 5 or 6 times within the first 10 minutes and see if any of these more skilled Gold players could stop him from just running over everything in sight.
Ghost To Lane used to do a series on YouTube where he'd take Bronze players and put them in Diamond games. I was quite surprised that they actually held their own. I remember one even pseudo-carrying a Diamond game simply because his team managed to get him a nice lead. I mean these players were way more skilled that he was but it's kinda hard to "out skill" someone when they are like 2000 gold and 3 levels ahead of you.
