Yes, I get it, narrow approach, so only a few can get through at a time. But why on earth don't more arrive when the initial few are inevitably slaughtered? I've been trying to wipe out a lair of tundra bandits, and they keep killing my small group of knights with their ranged weapons. There's nothing I can do, knights are among the most powerful troops in the game and there's no way to use tactics to divide the enemy and fight only a few at a time. They all shoot at us all the time, and they respawn all over the place, so nowhere is safe. I've been at this for almost an hour and this lair is literally impenetrable. The kings and lords should get these instead of their fancy towns and casles, then their kingdoms would be safe for all eternity.
