sorry if this analogy sounds funny.

I have come to the conclusion that warmaster combats, because of large "shock troops" such as cavalry, can become a little bit like getting one of the last matching sets of cards in RISK. Its late in the game, your opponents have all but 7 countries, you are down to 10 armies, but you have a set of cards to turn in.....you put them under the 35 armies spot on the board and conquer the whole world in one turn!!!!
BUT you demonstrated a skill in doing so, you mapped out a route that would allow you to continue on and on and on without getting pinned anywhere, you swept across the entire board in one swoop!
So I always think about that whenever my chaos knights attack. They get only 2 charges, so I need to maximize how to kill as many units as I can with those 2 charges, in the same manner as I planned on wiping out the whole world in RISK. however, I have come to the thought of Time. 2 rounds of combat could be assumed as 1 hour, just like each turn is thought of as 1 hour in the day.
I fell victim to growing up with that RISK maneuver that was part of warmaster that now I feel threatened as it might be taken away but I want to just come back and say, I understand now. It definitely changes the game, in a huge way, but actually makes sense to me now.
I wanted to say something as I don't think I am the only one with the limited engagement rule. Hopefully this helps others see it from another light.
