(Setting aside the red/blue solution, whether by noodle color or tape,) I'm curious as to why most people seem to be advocating the "+2/-2" solution, rather than simply a "-4" to the alliance with the unprocessed litter (rather than +4 to the opposite side). Can someone explain to me why "+2/-2" is better - as an incentive to avoid unprocessed litter, and also eliminate the benefit of TNA - than "-4"?
