Well, for almost any melee-build, you're better off adding some martial adept levels. Warblade might fit the bill for this one, since it is somewhat Int-focused. You could also drop the Int focus, and go Swordsage and focus instead on Dex and/or Wisdom. Going for a Dex-based Swordsage should also make it more playable from early levels, I think. Hopefully some other people will chime in. I am very limited in the time I have online lately. Glad you like the build, though. I did too, though I never actually got to play it.
