If we have dynamic queue ranked, please consider these ideas for solo players.

1. Let there be a separate queues for solos/duos and trios. Please, don't let 4 or 5 stacks into ranked. It will destroy the integrity of ranked. In addition, allow trios to only go against other trios. This way, the game is balanced in terms of matchmaking: solos/duos only on a team against each other or trios+1+1 or trios +2 against each other.

2. Have dynamic queue but give solo/duo players a solo/duo rating and anyone who is in a 3+ group a party rating. This way, at least the solo/duo players can be recognized for being solo/duo players.

Otherwise, there is no way to know if you are being carried or not. A duo is fundamentally different than a 4/5 stack and doesn't really destroy the integrity of ranked. A 4/5 stack makes rank much less meaningful.
