Gun Slinger 4, though the nerf to Deadly Aim hurt this class. That nerf that only existed after they introduced guns to the setting when they already had wizards and sorcerers taking advantage of the feat since the games inception. Yes, I am bitter.
Slayer 3.5. It is a good class.
Swashbuckler 5. It reads like it should be a 4, But Panache makes it overly MAD, in my opinion, with lackluster returns in comparison to what other classes often get for being a bit MAD.
Shifter 5. I wanted to like this class. Really it should have just been wild shape on a warrior chassis and not what ever this is.
