At least the actual encounters I put together mostly worked out, although they wound up being too easy. I think I need to be able to threaten more of the party at a time, between having a 5th PC and some extra homebrew floating around I was basically just picking on the Fighter, although I guess that's sorta his job.

Hope you guys' campaigns are going a bit smoother than mine.
