They say they are already doing "something" by catching people that are Boosting accounts via Logging into someone account and playing on it. Honestly I'm not sure since they don't give us numbers.
The only way left for people to boost "legally" is via Duo queue if you are lucky to have a friend that is higher queue you can duo with him and see if he can carry you up to where you want. There are even sites you can go on and pay a booster to duo with you on a smurf and get you to where you want. I checked last night, and for me It would cost me around $70 to get me to gold V if I wanted to pay for it.
Not only that it would try to even things up by making the Duo Queue's team harder than usual, this is fine for those two but the Three Solo Queue players that are chosen to fill out the team are going to be Victimized in that game. You'll most likely be laning against a player that is higher division than you because the matchmaking system boosts your team MMR to make up for a Duo Queue's advantages. If you loose your lane (which is likely since they are all going to be tougher) you're going to get flamed by your duo queue, worse if your Duo really doesn't belong in your division he's gonna get wrecked, feed, and be dead weight.
Duo Queuing the system as is now is fair for the DUO QUEUE ONLY, and it victimizes the 3 solo players that are forced to play with them. During the past month people are looking for any way to get to Gold V, litterally every game each team has a Silver/Bronze duo queue with a smurf boosting someone to Gold V. In these games it is not about you and if you can carry, it's about who's Duo Queue is better or who's smurf is better because the more skilled duo queue is going to carry and you as the player have little to no influence in the outcome of the game. You're basically forced to stand back and pray.
