Yeah, silly people for thinking that heroic martial characters might be able to do anything. They should be sticking to their 20ft speed platemail, standing there swinging for +2 with one weapon and dying, while the Clerics become Avatar's of Gods and Sorcerers create pocket dimensions full of Pokemon and bat crap for their middle-fingers to reality.ToB maybe is not overpowered... MAYBE
maneuvers & stances are a bit too much.
i mean, some of them provide you with abilities that only a feat could provide... so... tolerate people whos out there who hates or dont approve ToB.
In response to the OP, though; why Swashbuckler? If you're using a lance, you won't be using Dexterity. And if you could, why one level dip? If you're going Swashbuckler, it's generally better to see it through to third for Insightful Strike.
And also, if Tomb of Battle isn't being used/not allowed, why are you using Desert Wind's legacy sword? You know, that martial style from Tome of Battle?
