I think that's for two reasons. For one, they're new, which is always fun. For two, they seem, in some ways, to be more easily grasped. I'm sure they're just as deep and intricate as Talad and Laanx, but you can say, Dakkru is the godess of death, and Xiosia is the goddess of nature, or whatever, and while that's not all they are, it's not hard to understand. Whereas Laanx and Talad area little more ambiguous.
