I love it!
I have a question:
Did you use the 2nd level Corruption Corpses, or the 4th level ones from the MM? I threw a couple of them at my group recently and they struggled quite badly against them with the weakened state they add on, and I was wondering how your group found them.
That's a big party - or two small parties. Ours is 7, and big parties definitely change 4e a little. What's your experience dealing with 8 PCs?
Is one warlord inspiring and the other tactical?
Action points must really be something...
