Me and c2 got in a game today, 2000 pts, loot, chaos vs. imperial guard, using the two armies I posted recently. We didn't calculate the margin of victory but it was a sure thing that I had won. The collapsible infantry line worked well, with my anchors of armor surviving to do pretty good damage to the chaos units. There were several close calls, however, and c2's terminators were poised to smash my army's core to pieces, but my command HQ junior officer survived just long enough to leave them stranded out of assault in my turn for heavy and special weapons to wipe them out. I might have inflicted a few assault kills myself if I had a hidden-pf commissar embedded in my line. I'm considering switching him in for sharpshooters. Bah, I'm so fickle about that damn doctrine! Both the basilisk and leman russ had to beat a hasty retreat in the face of the demon prince but he himself fell back to chase a hellhound threatening to take an objective. As regards the elements I had changed up in my guard list recently, the sentinel autocannons weren't particularly effective but I did like them in the fire support squad. The veterans performed brilliantly, with some good plasma rolls. I came close to discarding one of their shooting hits - almost forgot the BS4! They wiped out the 5 remaining possessed to a man, who was then finished off by indirect fire from the basilisk. Unfortunately they were soon charged by two berzerkers and they got mopped up pretty handily. A power weapon in this case wouldn't have made a difference but I'm thinking about giving the vet sergeant one with a bolt pistol instead of his bolter - only 5 points after all, and a bolt pistol might get one fewer shot but 4 buried power weapon attacks might help them earn even more points back. I might even work in hardened fighters for them somehow as well. All in all, a good, fun game.
I did look over a summary of chaos codex "rumors," and I'm not as enthusiastic as I was before about my army making the transition to the new edition. To make an effective conversion, it will probably involve more buying and painting, and that pisses me off.
