Second, I tend to deploy wardancers behind and slightly off to the side of an attack unit. They can bound over and deal a devastating attack. Against armies without shooters, think of wardancers upfront. Start the enemy day off with shadow coil followed next turn by a nice nice flank or read charge. Remember, you won't have rank bonuses often set up to deliver flank or rear charges for your main combat units.
Scouts are interesting. .
I would field them in my own deployment zone with fast moving armies that field a large number of units . . . Your units are fast, have high leadership and don't need to present concetrated targets. Deploy so archery can be concentrated or can cover the vast track of the board. Most mportantly, don't be afraid to run, esp through woods at your oppnent or away from him. WE charriots are phemoninal.
