I'm glad that someone does.I agree with this criticism.

W&W compromises by telling you what the abilities do, without much reference to rules constructs. Personally, I find it amusing to read the rules and then read the UP reference and mentally say "no, that's the [x] power" with specific extras, flaws and drawbacks, but I'm quirky like that.Certainly, the pdf of Freedom's Most Wanted (which still hasn't been updated to correspond to the changes made in the printed version of the book) has this problem, and I believe Warriors and Warlocks has it as well.
But Warriors & Warlocks is equally useful with or without Ultimate Power.
Freedom's Most Wanted, Paragons, (probably some others I'm forgetting) and a wealth of 3rd party products use a number of Ultimate Power constructs that could just as easily, and more usefully to customers, be done with the core book.
