3.0 OA Samurai.
>mechanically atrocious
>a near-clone of the fighter, except worse by having their first feat replaced by getting two masterwork weapons, and their bonus feat selection being much more limited
>losing a sword makes you dishonored (can no longer gain samurai levels, loses any magic sword abilities), and also performing any chaotic act also makes you dishonored

>in exchange, the setting goes out of its way to nut over the importance of samurai and how everyone wants to be one and how anyone who's anyone has at least one level of samurai

No other class lets you strut around with the same level of daisho energy.
