do you regret removing smurf queue now the sentiment is going back to complaining about smurfs in every game.
Grouping 9-10 smurfs and the occasional late player to ranked kept the average game integrity higher compared to spreading those 10 smurfs out into other games
No, because the way it was implemented was making the experience pretty unreasonable for any of those late returners. There are other tactics we should use to improve game integrity that don't have those other painful effects.
