Mechanically, maybe. The class will still be called Fighter, probably, or get a new name entirely, since "Warblade" just doesn't sound like a core class.
I agree. Its a huge mess as-is, with Half-Celestial, Half-Dragon, and Half-Fiend as templates but Half-Elf, Half-Orc and Half-Ogre as races.
If they're really for streamlining the system, they should condense all if it into a single set of rules for making a half-race template from a base race.
