That was quite unlucky, I would say though that it was partly down to your army as well, not just your dice rolls. The only real threat to my vehicles was your preds, which I concentrated on for most of the game to get rid of them or at least stop them shooting. The only other real threat was your attack bikes, but as you used them very defensively (you probably wanted to keep them for last minute objective grabbing) they didn't really fire at my tanks, fearing any return fire.
My luck at the heat this year was fairly average for once. I can't really think of anything that stood out as seriously above or below average. The only unit that seemed to have a slightly unlucky run was the fire dragons, but they weren't performing that badly.
