It's a different army list with quite little available variation and some stark oddities that show its poor playtesting. Just look at the ovemighty Magma Cannons, grotesquely costly great weapons for Infernal Guards and K'daai Destroyer without any weaknesses. This is however not a strong enough reason to disregard the Legion of Azgorh CD list.
I understand if tournaments won't allow it, but outside these it should be no problem playing with the LoA. This hobby is about having fun, and I'm sure most of us have enjoyed playing with or against odd, variant, thematic lists, such as Zombie Pirates, those found in Storm of Chaos, or any number of unofficial variant army lists published in WD.
Merely the fact that LoA brings back Chaos Dwarfs as a playable faction makes it deserve a chance on tabletop. Of course, I'll build my CDs as Dwarf-proxies, but I'm sure LoA will find a use in my gaming group in the future. It is, after all, quite hard to proxy a Skullcracker if GW won't bring in the Dwarf Deathroller come next army book.
