Ok just tried KoW 2 at 6mm and not overly impressed, hopefully i've just missed things.
Did ~1400pts dwarves vs elves. 1400 just because that looked about right for 6mm fantasy armies, for dwarves that meant:
Ironbreakers (regular warriors) horde
Shieldbreakers regiment
Rifles regiment
Rifles regiment
Berzerker troop
Berzerker troop
Bear riding berzerker regiment (these had some other name in KoW)
Bear riding berzerker regiment
Standard bearer
Berzerker lord on a bear
which looks like this:

The terrain rules seem pretty weak and are poorly set out (there is a terrain section to the book, but the key factors for terrain are explained in other section and not the terrains section …). Can't see much incentive to use terrain except to block LoS unless your unit can ignore terrain when moving.
Since your opponent cannot retaliate when you charge them, but must wait until their turn, alpha striking stuff to death immediately on charge seems the way to go? You start 24 inches apart and horseback cav can charge 18–20 inches. So anything that moves out of its own deployment area is asking to get smashed.
Why would you take anything that isn't thunderous charge cavalry in this game?
Shooting is pretty limited as you move charges before you shoot and cannot then fire in to combat. So no means of softening things up before a charge.
Magic system is nice and simple (big positive for me) and I liked the magic item/wargear selection.
By the time id drawn the lists up I was really looking forward to it and was prepared to give no casualty removal a chance … but this just seemed poor. Can only assume i've missed something key, or that playing it vs another person somehow fixes it. I'm all for abstracting and simplicity, but i've got to admit this is lost on me.
