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

[Boci]

I think you're over selling avalanche of blades and scything blade. AoB only really shines for a combat rythme warm up, for normal melee attacks I would hesitate to even mark it blue, and scything blade just gives you an extra attack as a swift action. Flashing sun is a second level maneuver and its arguable better since you trade -2 to hit for a swift action.
