There are a lot of nice options here, but I can't bring myself to give this a higher rating because of uncorrected mistakes. It reflects poorly on the entire work to have a non existent feat listed as a prerequisite for this long without an official correction to the content. I understand that mistakes will be made, but for this to have been out for a full year and still not see the prerequisites for Blinded Master fixed in any way. No errata, blog post, or FAQ entry. Mistakes happen, but I can't believe this has not been mentioned before with the amount of time it's been out and the number of rules lawyer people who play this game.
