I just finished reading this, I love it. One question, though... can the Combat Style feat count as the prerequisite for some of the more advanced feats such as Greater Disarm?
PP sent you a PM so you would at least see this.
Not so simple answer...in a home brew campaign I would allow it. Here is why, due to the massive prerequisites needed, and if you take Improved Combat Style. At which point if you decided to specialize further, Greater XXX would be met, and the PC finally became great at one maneuver.
However, some GMs may argue that you are too broadly trained with Combat Style, and improved trip is still needed for greater trip.
I know it's a little late, but ask your GM for good measure. Hopefully that person allowed it. If not give them a Horn Toss.*
The way the feat is designed is so that you may perform all CMs without any issues and not need all the improved this and that. (we should probably develop a Greater Combat Style feat...)
*We do not condone or endorse anyone preforming a Horn Toss outside of a tabletop make believe game. Don't do it. :-)
