I'd love to see armies bigger than 9 units... imagine 12, or even *GASP* 20 units in an army. You'd add a whole new layer of mayhem them. There would be carnage on a massive scale. Of course, we'd also require bigger tactical maps
. I would reccomend a max of 3 hero slots per army.
Army size 9 is pretty restrictive when it come to composition. Assuming the balance comes forth, we are looking at 1 hero, 4 archers, 4 melee units or combos thereof. With 20 units one could have a hero backed up by a front line of heavy armor dudes, a 2nd line of assaulty types. three units of cavalry and a nice amount of archers. And it would look amazing. That too.
