To start: Holy jebus, I love this system. I doubt I'd be able to finagle my group in to using it, but wow. It smacks greatly of ADnD prof., which I'm assuming was deliberate.
Here are my concerns: I haven't run over the mechanics too much, though they seem excellently well done. I am concerned by the fact that you base these abilities strictly on fighter level, though. That creates a lot of conflict in my mind. First off, I play AU, not 3.X, so there's not even a fighter to consider. I hate to think that, say, a mageblade is restricted from taking this. I'd prefer to see something along the lines of a BAB requirement, with fighters getting these for free at relevant levels. That way if Wally Wizard really wants to be a bad-aspirin with his q-staff, he can take Improved at level 12, when he has +6 bab. If Mikey the Mageblade wants to, he can add it, but he's not as good as the straight fighter, since he's getting magic enhancements.
There's also the concern that under this system, you would give up a chunk by taking a PrC. Flavorfully, moving to the Weapon Master PrC shouldn't make you *less* effective with a weapon than a warrior. And unless you're willing to revamp every PrC out there, it would be easier to look at the above BAB type requirements....
And let me re-iterate: Wow. Incredible job. Those descriptions of the various combats were just amazing.
Is there anyone out there interested in an Arena Fight type PbP game to test some of these rules out, and play around with them? I'd play, but not run, because I'm swamped.
