Is it just me, or are Crusaders the worst ToB class?

[cosmonuts]

Can someone show me a well-built swordsage who could contribute in a practically optimized T3 party?

This is my only swordsage sheet so far. Help me improve pls.

edit

Excuse my maneuvers if they don't add up correctly. I just threw this together to be approximately what a swordsage should look like at level 8.
