My friend has been watching the Valorant tournament and saw them splitting up. He now always forces to split up in 2s. We just play pubs so what is the best method?

Immortal teammate was dropping tons of Shorty's causing low server fps and tons of lag. Has this always been a thing or is this new? https://reddit.com/link/m26s3h/video/pgynmfzx99m61/player
