Note that I'm basing this review on the talents themselves, and not the pre-made pyramid trees.
The biggest issue I see with this document is that it all but reprints a large number of talents from the other official sourcebooks, with only very minor changes to the text. I'm not entirely sure how this product can be sold in this way based on this, as it seems very close to some form of plagarizing the official content.
Other than this, many of the talents are poorly worded, written almost as if they are first drafts and not fully fleshed out. For the price, the overall quality of this product is quite poor.
