Re: Teamed up with lower ranked players
You aren't only playing against gold teams. Some of them might be all gold but there will be plenty of players in your lobby overall that are between plat-bronze. Because if the game takes too long to que enough people into a match it pairs you with the closest to your rank that are currently searching for a match so you don't sit around waiting 5-10 minutes for a 10 minute game. This is only to prevent you waiting around forever in que. They announced this all over the place that match making will try to put everyone of similar rank together to diminish the que times, but if not enough are found within a specified time it will just put whoever is searching at that moment into the game.
If you want to avoid this the discord always has people looking for ranked matches and they usually say what rank they are looking for to que with. That'll be the only 100% way you get a whole squad at your rank.
