Well, if you look at the class that it was modeled after, it is within standards. It appears to be taliored after the fighter/mage class from first edition. Take a 20th level character in each edition and you get about the same amount of power and spells per day as a fighter/mage when compared to a 20th level duskblade. The difference is a full BAB with the Duskblade versus the full spell list of the fighter/mage.
I think I would prefer to see them have full use of the wizard spell list with a clerics BAB, which is closer to the class they are modeled after.
I am going to play one this summer in a new game, and that DM is kind of a dink for rules, so I doubt he will change the list. I however would alter the spell list or redo the class a bit if someone wanted to try one out in one of my games.
