I played my first game with the AT-ST the other day and it preformed pretty well I thought. I took it with a full kit (laser cannon, grenade launcher mortar launcher and Weiss, no comms). We were playing Intercept the Transmissions and it held down a pretty big field of fire on two of the objectives. The only issue I really had was that Weiss seems like he is only good for one turn if you want to be aiming or moving. Using a recover means I can't move or aim if I want to unload. I know Veers helps with the aiming.
How are people running their AT-STs? What has been working for you? What hasn't?
