The "anti-betrayal" measures have only gotten in the way, I've found. I several larger games in the past I've had, it's been two smaller coalitions temporarily banding together to fight a larger one that otherwise was guaranteed to win. It worked once, the other time I was on the other side and beat the two opposing coalitions down. This is now not possible. At the very least, right of way should be allowed cross-coalition.
