I also am sad that they brought back ranked teams for a short while then removed it again when the new season started. When playing 5v5 flex you can't pause, you don't get the team tag, you play vs other 5's that are not as serious as you are (in terms of playing as a ranked 5's team) and there is no separate rank for 5v5's so you can't really show how good you're team is when most people would look at your flex and just assume you duo/trio queued with friends to get that rank (I personally liked showing my ranked 5's team rank). To put it frankly, flex 5v5 is nothing like team ranked, there WAS a reason why when dynamic queue was around, people still asked for ranked teams to come back.
