What with having things like entire armies of monsters, like the Ogre Kingdoms, and armies made up mainly of things like skirmishers and archers, like the Wood Elves, and even entire armies of 'magical creatures' like the Daemons of Chaos armies, do we think that (ignoring extreme lists, like choosing an all mounted WoC army, which most lists allow to some degree) some armies are just unbalanced? Or are they just different?
