They're being added to the game via the Realm Of The Wood Elves DLC and I've had an early play with them. A big round of applause, please, for Total War: Warhammer's definitive glass cannons. When they aren't doing micro, they also do getting knocked flat by a gentle breeze.
Wood Elves, it turns out, really, really do micro. Micro? Well, I dare say some of those fancy northern Dawi tribes can find a use for it, but I've always set my watch by a good, solid shield-wall. Dwarves don't do manoeuvres, they do gunpowder and big helmets and spurning alliances because somebody's ancestor forgot to return the lawnmower. Or rather, you know where they are - all the way over there on that ridge, Ironbreakers in front, Quarrellers behind, Hammerers poised to waddle down the flank like a glacier performing a legal U-turn. Let me summarise my highs and lows as a Wood Elf general in one phrase: I'm very much a Dwarf guy.
