Well, for example, in Order: the first tier is already a ranged unit (position it further back and have it attack), then golems with resistance, mages with several spells, and dragons – either mechanical or with spells. And Chaos? Read my previous post. Who needs something that a rogue can bypass in the first tier? Where have you even seen this first tier?
Further on, there are Humans. The first tier is just cannon fodder, the second tier has fairly strong archers, and the third tier has either an archer catapult or an incredibly powerful pikeman. The cavalry is mediocre, but the angels are...
Nature is just cannon fodder, except for the mantises and elves, but you can summon a lot of troops.
