Its a good idea to have 2v1 and 3v2 especially for players in the top 3 or so who are much harder for lesser skilled/newer layers to beat.
At the moment i have 2 people refusing to play me because i beat them everytime
This would give them a way to win (or not lose by so much) without a 3person battle where they end up having to fight each other after (or if) i am beaten.
And as we all know, the usual winerof 3 person games is the person who waits for a while whilst the other players attack each other, biding their time.
