Is this RAW, or just "his intention"? I don't have the CW in front of me....
Well, no, in the class, it just says "feint", or "Bluff check", or whatever.
So you use the rules in the PHB, which says you add your BAB as well as any applicable modifiers to your Sense Motive check.
"any applicable modifiers" means things like Wis bonus, Skill Focus (Sense Motive), etc. Things that modify a Sense Motive roll.
But SoaP was thinking when he wrote the class that it meant "any modifiers you'd normally apply when you add BAB to something" - ie modifiers to an
attack roll, which fighters generally have a lot more of.
"So the fighter will have tons of bonuses to his roll to oppose the feint," he thought, "and so a feint before every attack won't be unbalancing."
After the class was published, and this line of reasoning came up in conversation, it was pointed out to him that no, the fighter
doesn't add Str, Weapon Focus, etc bonuses to his Sense Motive roll.
But he decided it didn't matter - it still wasn't unbalanced
