Seriously, how low must you fall in order to buy an MMR booster?
Just ran into a guy who, after, looking at his match history, is CLEARLY being boosted. I'm not going to name names, cause that's against the rules here, but seriously people. You honestly believe that getting a higher ranked player to play on your account will make you a better player?
Just wait and see what happens when that guy gets you to Gold or Plat. You will be nothing more than a glorified minion in EVERY game you play. I honestly believe that I don't belong in Bronze, but I'm not going to buy my way up the ladder in order to prove it. Not only do you ruin the games of the people you are meant to be matched with, you also ruin the games of the people in the elo you finally decide to stop climbing to, because the players in those games rip you limb from limb.
Oh, and did I mention that there is a VERY high risk of your account being noticed, and eventually banned? If that happens, guess what! You lost not only the money you had paid the booster, but also any money you spent on the account, along with the account itself! Let's see how you like climbing back up to level 30, cause I've heard it isn't a pleasant experience (especially if you show that your better than the average lvl 20 player!).
Rant over.
