I feel it is a good map for even the most experienced players as well. Sometimes you don’t have all night to play game of global. aa50 can turn into long games too, I had a few 24 hour aa50 games berlin and russia just would not fall, it was crazy.
Most turns take 5 minutes in all axis and allies games minus the rolling dice part. On crossroad rounds it is okay to think about things a bit, because you are deciding on a direction.
If you are take too long to do your turns, people tend to lose interest, get tired, or not have as much fun as otherwise.
If you really want to insist on min/maxing every little thing, I recommend learning statistics and probably on your own time so when you show up you can do the math in your head no problem as you go along. I use the built in calculator in triple a only for big battles in dice games.
Low luck games are another story, you have to do every little thing min/maxed and run every little calc, because you are calculating for next round and the round after usually. Dice games, you don’t know what your casualties will look like so you are always adjusting based on what happens.
