In Team games players queing solo or in smaller groups (2 players queing 3v3) can often get into a game against relatively similar Elos, but end up on Teams that are very unbalanced.
For example if There are Three 1500 players in que and Three 1200 players in que, the game may assign all the solo queing 1500 players to one team and the 1200 players to the other team in a non-sensical imbalanced fashion.
For example in this game it’s my understanding we had 4 solo que players and the isis/Posiedon players were together. However the game decides to put the 3 highest rated players vs the 3 lowest instead of putting a higher rated player with the two lower rated ones. This ruins a chance at a decent game.
