Your assessment is correct, yes. Your build uses my revised feats to make a build that would be completely ineffectual in play into something that's halfway worth considering. Since it's such a unique type of build that's worth some merit.
But, as far as you seeing that as a problem, well I surely hope you're the only one, because even a lowly Fighter Archer at 2nd level with standard, non-optimized feats plucked right out of the published PHB can outmaneuver, out-hit, and out-damage your build every single time. A Warblade with a Greatsword? Well, that just blows it out of the water.
