Warhammer, both 40k (Which DoW is set in) and fantasy have some of the most amazing lore, its on par with Tolkien and LotR.
There are 3 factions that have been "shown" in the trailer but 10+ factions in the actual Warhammer 40k universe.
Melee is a huge part of Warhammer, and to are guns.
Yes there are gigantic units.
Yes it did change.
Its very rich in strategy and generally better designed and balanced (since its fantasy and isn't tied to anything).
