Think about it...5's is to laggy whenever there's a group battle, Duo's has great gameplay but there aren't enough ppl (group wise) like in 5's. I think 3's would be a great addition. Perfect amount of people, and the game would be able to handle the team battles like in duo's, there would just be one more player added to each team. Either fix 5's or just cap it off to 3's for performance issues. Let me know your thoughts.
