Only way to fix this is with smaller maps, tbh. Issue I see normally when I log in around 6pm est on weekdays is 2 sides fighting each other with big dars across the map, while the 3rd team is taking bases undefended. It seems like having fights on all fronts is a rarity. Apparently either both sides are attacking knights, or both sides are attacking Bish.
That's normally how I see it, but don't get to stay on long enough once the later evening crowd rolls in.
