This is making an Evoker a core class. It is okay if you want a new core class. I'm happy with things as they are
[3 of 5 Stars!]
Just a note for anyone who may read this review and believe the product is somehow deceptive regarding its contents:
The product description of EVERY item in the Core Specialist Wizard series clearly indicates the product takes a respective specialist type and presents it as a 20-level core class, with accompanying additional materials. It's unfortunate this wasn't what you were looking for, Mr. Avaritt.
I can see why someone not wanting the specialists to become core classes would not like that aspect of this product. However, I don't see how anyone could expect anything else when the title is "The Evoker: The CORE Specialist Wizard" (emphasis mine) and the product description includes (among other indicators) "Each product of the series will present a different specialist as its own core, 20-level class" I don't think we could have made the product's contents any clearer in this regard. I hope that you will at least get use out of the feats, PrCs and magic items.
