I'm not Generals expert, but I played GLA against a Super Weapons/Laser general (forget which), and I couldn't touch him at all.  He knew it, too, he likes to play around with strategy games, so he let me build as many units as I could.  I tried all sorts of different long range stuff, but none of it could get close enough to do anything.  Once your big ass force is squeezed into a tiny little ramp there isn't much you can do.   Overall, I was displeased with how weak Dr. Thrax felt compared to all the other generals.  Any strategies for playing as him?
