Nah, you underestimate your power, FAJ. My first attack on your capital clearly showed how brutal Shadow Blast / Clouds of Death are. Sending my men in without a plan would be committing suicide (twice!).
Fear not, the assault crew is on the way.
As for the attack at the southern fort, that was a cheap shot to see if I could take it. If my mages hadnt run out of spell script they'd have killed all your sauro's and I'd have won. It was worth trying.
