First, they aren’t “so called”, a smurf is a technical term related to Starcraft since SC1 (cf. first post).
Anyway, your are right, there can be some good consequences for the opponents : confront ones’ strategies to a higher league metagame, observe the reactions in case of cheese, observe the execution, realize the gap in mechanics.
Yet, to have a shot at getting all of those benefits, you have to have full control over your frustration, and analyze your losses with a cool head. And… regular users are no better than smurfs at this. Think about it : if some of the smurfs themselves couldn’t handle the frustration of playing a fair game, how much more frustrating could it get for someone who understand he’s been played an user who bypassed the matchmaking to bash noobs, and who will earn L2P noob trashtalk after the game if not during ?
I’ve played competitive games without matchmaking. Let me tell you that when you double perfect someone in a fighting game, rage is most of the time the only reaction you will earn. The truth is that the very reason for a matchmaking system to exist, is to be matched against opponents of comparable level (a bit stronger, or a bit weaker) so you can train efficiently. If GMs were to face 4 bronzes before having the opportunity to face another GM, it wouldn’t be good either for the high leaguers (inefficient training), nor for the low leaguers.
If one does want to bypass the matchmaking, he can do so on a custom game.
As someone said on the other thread :
That can indeed happen, though in fact is also often related to Provisionnal MMR mechanics, where your MMR fluctuates heavily and your displayed league is way inferior to your current one.
Yet, there are some users who enjoy into defeating their peers while having the frame of a lesser league displayed. I’ve seen one named ***Bandit (I won’t provide his full gamer tag for the sake of him not getting targeted), who had freelost to rank himself in bronze, and then climbed all the way back to his M1-GM league while playing unranked. Hence winning GMs while officially being a bronze leaguer.
The few tools I provided in the first post can help identify those of them who choose to stay at a level lesser than their real one. And so cool one’s mind by knowing if you can say for sure that you’ve been really smurfed.
