3. I didn't like it because i had a melee unit protecting it, but the enemy killed it and my ranged unit would "fill the frontline". When my turn arrived i couldn't place a melee unit in front, and if i placed a melee unit behind it wouldn't advance when the ranged one died.
My opinion:
I think units should only increase score if there is no enemy on the same column. So melee units should attack ranged enemies in the back row if there is no one protecting them. I think the difference between ranged and melee should be that ranged can attack from the back row but that's all.
And i don't think ranged units should advance, meanwhile melee ones definitely should. What kind of archer runs towards the swordsman and what kind of swordsman doesn't chase the archers?
