Boosting is a problem with very good players creating new accounts and playing ranked. Or really good players, logging into another person's account and playing on it. That's not really related to dynamic queue or the potential problem it causes or if it has compromised ranked integrity. Smurfing and booting was a problem before dynamic queue was implemented.
I don't think dynamic queue has really exacerbated the problem much. Unless the player is Diamond plus boosting Silvers to Gold for rewards. This does happen, but I think it is less prevalent than you think.
I don't know about how other upper elo players feel about DQ and their experiences, but I am Gold I and I can't single handedly carry my silver friends in ranked games.
I am not that good, and they are pretty bad. Meaning, I can't consistently win games for them to boost them to Gold. I am sure a lot of Plat players can't boost Gold players to Plat easily, and as a higher Elo player, playing with silver and bronze players can be frustrating sometimes.
They are my friends and I enjoy playing with them. But because they lack skill in the game we can't win as often as you would think just because I am Gold I player playing on a Silver account.
The people that think boosting is prevalent because of dynamic queue are the same people that just can't win games as often as they would like to get them out of whatever Elo they are currently in. They think they are better than their rank.
Hourly people create threads on this forum claiming that they hate dynamic queue and that they played against a 5 man premade and lost because of it. Then they go on about how dynamic queue is ruining their ranked experience.
Occasionally when I see these threads, I look up the game they referenced and the match history of their opponents. About 70% of the time their opponents have no history of playing together, in previous or the next game. 30% of the time they are simply duos or trios.
Still they lost the game, think it is due to a 5 man premade, blame dynamic queue because they already do not like dynamic queue, and it reaffirms their existing predisposition on DQ.
The reality is that they are not very good, the opponents are not a premade very often, and just because an opposing team appeared coordinated does mean they were a premade.
Their lost had little to due with DQ, and probably had less to do with boosting and more to due with smurfing.
Bad players play the blame game a lot:
- They blame teammates
- They blame the queue system
- They blame the opponent's coordination
- They blame boosting
They almost never recognize that they themselves are not that good and could work on their game. They simply think that something else is contributing to their inability to win games.
