Wow, sorry I'm late responding to everyone. I didn't think I'd get so many comments today. And I guess I was wrong with letting the Monk use Flurry with it. That might explain things a bit more. Whoops. I'm still new to PF let alone GMing. We are all new players and this is just something kind of thrown together that we enjoy. No real min-maxing at the table.
The Monk has really out-shined the fighters due to the dagger + Flurry. Now reading these comments, that might seem to work itself out by removing Flurry from the dagger. I'll have to see how that pans out in our next session. Sorry for the late replies, all.
Also, another thing that really makes the Monk shine is the Daredevil Boots that she has. (Yes, this is all self-inflicted, I know.) They aren't crazy broken, but they do make her able to jump around the field without many AoO on her. The Bleeding stacks on many people very quickly.
