Items I consider a positive for enhancement are bolded. Items I consider a negative are italiced. More positives than negatives I guess, but There isnt a lot of zing.

I don't see anything about the change to Str/Agi AP or about the nerf to Agi's crit contribution. That is the biggest change right there. The elimintation of natures guidence means we need additional Hit as well. Mental Dexterity makes Int usefull as well, and makes the change to Ancentral Knowledge a good one. Plus the talent now makes sense in the Enhancement tree.
