That is a bit of a departure from normal class ability listings. The table might not look as pretty, but it would be useful for anyone reading the class-at-a-glance to see the extra uses. The same should probably apply to the Crimson Slash's alternatives.

The abilities themselves look fair individually, though I have to wonder if the bonus feats aren't adding too much to the class in total....
