That idea gets brought up every so often in westerosorting and I generally agree with their decision not to handle points that way. The main reason being, I feel it would pressure people to either do their share or quit the game entirely so that they don't drag down their team. I want more of a laidback system where people can be inactive pointswise as long as they're enjoying the comm in other ways.

So basically, I would rather have alliances than to do point-scaling by team size, if that makes sense.
