Unbalanced teams due to smurfs
I don't know how often this happens to you, but very frequently the matches I get are overly one sided due to smurfs.
We're talking either my team gets 2-3 smurfs while the enemy team gets none or vice versa.
Matchmaking mmr is supposed to match equally skilled players against each other. And they've also done a good job to considering filling equal amounts of autofilled people on each team.
My question is: why can't they do the same with the number of smurfs on each team?
Clearly, 3 gold/plat players being placed in the same team against diamond/emeralds isn't fair. Although their mmr says they should be diamond, they are far from having reached their actual peak. And in most cases, they're actually masters or even grandmasters.
Having such unevenly matched teams, although the mmr threshold is met, leads to just unsatisfying games, where one team hard stomps the other in under 20 minutes. You're not having fun, and you also feel like you've had your lp robbed.
