"Degenerated" carries a connotation of "becoming inferior." It's not at all clear that a relative lack of irregularities makes a language inferior. One might even say that it makes the language superior, at least in the sense that it's easier to acquire as a second language. (First language learners don't seem to have that much of a problem with irregularities, although the gradual loss of irregular forms probably means that the problem for first language learners is not null.)
