I love this game, it's one of my top 5 games of all times. And reading things like this makes me love it even more!
This is a totally different tactic than I've used, and it works well. I love how every person playing uses and figured out their own way of beating the game, and just how many combinations and tricks you can use.
I also love the perfect ammount of randomization, forcing you to change your tactics/troops based on what's available and where you are in the game.
Also, I will try out some of the things you wrote here in my current game
