Dynamic queue is a form of Elo Boosting
It takes hard work, commitment and buckets of blood, sweat and tears for players to earn a high ranking in League of Legends. Boosting devalues the commitment that many of our players make to earn their rightful place among the worlds best League of Legends players. Leagues system has always been carefully tuned so that players are placed in the proper tier with others who are within a similar skill level. If a players MMR is boosted unnaturally they will most definitely falter when they begin to play ranked at that tier. If a player is unable to keep up with the other higher MMR players in their match they will most certainly degrade the game experience for everyone involved.
