Still, some of the Tiger Claw maneuvers seem fitting even without TWF, like Sudden Leap for example. I think I'll just disallow Extra Granted Maneuver. That should be enough of a nerf to tone him down to crusader level, I hope.
It's not so much MAD itself that I dislike; picking one thing to specialize in is fine, like swordsage can do. But for some of them, it's just that there's almost no reason to take a stat since it only affects a small part of what the class does. Cha for rangers, for example. You get Wild Empathy, but nearly nothing else, and you have three or four other stats you need so there's almost no reason to take it whatsoever. If I can get two or three Int-based abilities for swashbuckler, then that would be fine, but if it's just one thing then it'd be a problem and a waste.
Insightful Strike didn't remove that though, since you can still Power Attack with a rapier or just ignore Insightful Strike altogether since Power Attack does more damage.
I see three different combat styles for my idea of "swashbuckler"; a sword and dagger (TWF) style, a sword and shield (it's called swashbuckler for a reason), and a one-hand sword style. I think all three of those are supported fairly well, though you're right that Power Attack is still an option. What about going with 3/4 Bab? It would weaken the class a lot but it'd also let me give him two good saves as well as enforce the idea of "mobility fighter" by making full attacks less effective. Power Attack also becomes a lot weaker with less Bab, so you're more dependent on maneuvers. Extra Granted Maneuver might not even be so overpowered then. PrC access would be harder though.
I don't really want to remove the possibility of TWF and sword/buckler. If it came down to it, I'd rather allow (but discourage) Power Attacking than disallow these styles.
Same here. *shrug*
I'd rather not push back Grace, if only because of my sense of aesthetics, and kicking back Weapon Finesse just screws over 1st level swashbucklers that dump Str. Meh, most ToB classes are really good dips. Two level swordsage for Quick to Act, Weapon Focus, Wis to AC, two stances, and a lot of maneuvers. Doesn't bother me that much in comparison.
Yeah, I just used the warblade's stance progression. Much better.
I see what you mean; some of them are overloaded with features. I'll try to cull out some of the useless ones.
On a side note, a lot of the favored enemy abilities are a bit of a stretch (literally, in the case of aberrations). If anyone can help me think up better ones, that'd be great.
