What if you're Gestalting, and you combine Samurai with Rogue? You get tasty TWF as class features, saving you feats, you get better BAB and Hit Die. The intimidate based abilities stretch you too far for which stats you need, but if you ignore them you might as well go fighter so you can TWF with anything you want, like two finessable weapons instead of a Bastard Sword and whatever the wakizashi counts as.

So for a low Dex Rogue//? build, Samurai is good. But why are you playing such a thing?
