Masters of the Sword: A Warblade's Handbook [Under Construction]

[Greenish]

Dragonborn is what is required for DFI in the first place, otherwise you are blowing a feat on Draconic Heretage or something, which gets really expensive.

Yeah, but what does human do with Dragonborn?

Also, if you go dragonborn (not necessarily silverbrow), you get to choose your heritage, rather than requiring a dip in Sorcerer for the privilege. Thus saving a feat there as well.

Whether it works for DFI depends on the DM.
