After looking at this more, I think I'd have to agree with EMR on this one. Yes it is much better than the old AT-ST. HOWEVER, we know for a fact that Rob was aiming to make new Huges more playable, so it should be better than the old AT-ST. How much better is the question I guess. The Rapport 10 seems to indicate that BS1 is about 10 points better than the UH AT-ST. That sound about right? In my mind, the combination of Charging and Twin is crazy. Granted, Rigid still restricts that a bit, but it opens up a ton of possibilities with Thrawn now, since you don't necessarily have to waste an AT-STs activation just to get into a position for swapping.
So, I can see the creep a little bit, but I have to say that this is the only one that appears that way to me. Since it's Unique, and will only be found in the $50-$60 Hoth pack, I guess Rob and Co. felt the power increase was OK. Although....unless Luke's Speeder and the Golan Arms Turret are pretty powerful, the balance for Hoth scenarios just tipped farther in the Imperials direction.
And I just noticed the way Veer's abilities are worded. WHEN you activate, so at the beginning of the turn, there must be a trooper with 2 squares (basically adjacent), but the Fire Support Mission doesn't happen until the end of Veer's turn. I'm thinking it won't really be all that hard to play defense against that guy. We'll see. It is going to annoy Super Stealth squads. Perhaps Holo Veers and Vader Unleashed is Rob's solution to SS ruling on Korriban? Other cool thing I realized is that Veer is still subject to Thrawn's CE, so you'll be able to swap him around if you need to get him into a better position!
