+1 to idea with formations. It does look tempting.
And I would disagree with Rusbear who says that the game is luck based. All you need is a well developed risk management strategy, and luck % is way less involved compared to real life. I do hope that developers are not going to eliminate the chance of random lucky hit with 5% chance to hit. I personally would not appreciate that, because “the strong influence of random” makes it so much more fun as so much more replayable. I personally would not like to see chess with 12 battle brothers.
