I've done the formatting, thanks for the tips.

I changed mettle to include will saves. It seemed more reasonable to me to have experienced fighters develop extra-tough bodies than extra-tough minds. On the other hand, it seems to be causing confusion, and "will partial" effects are really rare.

As for who enters it, Warblades and Swordsages who have had a change in perspective, of course! There's nothing you can look down on as harshly as what you once were.

As for power, I think the early levels are a bit weak, so there's some nice stuff at the end. Strike-on-strike can do a huge amount of damage, but it also runs through your maneuvers pretty fast. Besides, you'll be at least 15th level -- gotta keep up with the wizards somehow.
