It doesn't make much sense to me to give the conjurer the high-level resurrect spells, since it is the thaumaturges, not the conjurers, who are seeking a means to bridge the gap between life and death. This new change to the battle/class system doesn't seem to fit well within the established mythos.

I mean, in this game world, the secrets of life and death are still unknown. Raise spells should be difficult to access, and really only accessible through the thaumaturge's guild at high ranks, as part of the guild story line.

What irks me aren't the changes themselves, but the incongruities they cause in the story.
