Remember why militia was added in first place: to protect people who want to stay inside the town, because they are in weaker standing from pvp point of view, it's easy to scout players who are inside. This rule hasn't gone anywhere so either you nerf militia, or remove it and add some other temptation to stay inside or just don't give a damn the whole subject. That leads to the controlling faction always evacuation to worldmap, leaving the town empty. But guess that's least of the problems.
