It would take ages to exhaustively address this; overall I agree with it though definitely not with everything.

One thing I definitely disagree with is that N rating on the Water option for Nature's Weapon. Self-enchanting throwing knives that you can recreate as a free action pretty much solves every problem with throwing builds for one talent. And then you can grab the Mage of Ice and Rime feat and create any weapon you're proficient with, or get free-action reloads on guns and xbows and stuff. It's a lot more powerful than you're giving it credit for.
