One thing I learned is that in KB you rarely ever use the same troops for any long periods of time. Think about what you are using royal snakes for ( tanks, range attackers or quick killers) and look for other troops that can replace them. Save your game and try out a few new ones, use auto combat and see how the AI uses them. If you don't like what you see reload and try again. At the moment I am using necromancers , vampires and black knights with griffins and dryads but I am done with the demon areas and need to change troops again. Remember that new areas may need new styles of fighting.
