Honestly I prefer the format of the original blog post, glad I didn't spend money on the PDF or i would want a refund. why did you include all kinds of feats that you didn't change? It makes it harder to tell what has and hasn't been altered, the pdf just feels like 30 repeated pages and pulling out the actual useful changes is no longer worth the effort of referencing yet another overly long document. (leaving this as my first reaction)
finally saw the appendix, that is not what they are usually used for. I still say the first 30 pages of the pdf are pointless. the whole thing could easily have fit into 10 pages and still had room for you to explain your choices and alteration like you did in the original blog post. you wanted to profit from your otherwise good ideas and turned them into a bloated mess. I like well reasoned arguments and thorough explanations and was expecting more of those, not mostly filler. Do I understand why catch off guard now has prerequisites? Do I have any idea why you feel hamstring is balanced?(or even makes sense, you don't walk off a severed hamstring.) changes without explanations aren't useful, the WHY matters even more than the what, but you ignored it completely.
