Well, we only had 7 players this week and my primary DM (the store organizer) ran. I decided to play instead of go home with a half-orc scout I specced for killing large monsters. We killed the Dragon in the top of the second round when the Half-orc slayer who went first hit it again. The DM doesn't read these threads so he just let the Dragon take a standard action on its Instinctive rampage (including breathe). It was ugly. Most of the fight, the dragon was dazed, immobilized, prone, -2 to all attacks and defenses (my Hellfire and Brimstone), -7 to attack anyone but the Knight (aura and Glowering Threat).
