I can't wait for the elves. I plan to shoot and shift with archers every turn, makes them very elusive. The scion of Amyhel (sorry butchered that) will immobilize and stun pursuers while Alianna and Leonx riders hunt down the rest of your army. I love the mobility the elves bring and the anti mobility the scions put on your opponent.
I assume at some point elves will get a more melee infantry.
