it would be up to the players, a game could be 2 vs 2. or 2 vs 1. splitting the points obviously. it would make the games different.
but the big advantage is when some can't make it to the campaign night or play a game, their team mate can. which would make the campaign run smoother.
not every one needs to be in a team, it would help those who have limited availability.
that was the other thing, it would reduce the over all games that need to be played each round.
anyway just an idea.
