The SWMA4 uses the same format - for instance, the Heralds of Night are listed as Fighter (Warrior, Evil Paladin). Terry provided the profession for those who used RM2 without the companions (core only), and (optional) professions for those who used them.
Personal opinion : I think RoCo 1 and 2 are OK (even if the Warrior Mage from RoCo 2 might require a slight nerf). Starting from RoCo 3, there are some professions that fit the world, and others that do not, or less obviously so. But Shadow World is so varied that you could conceivably include them anyway and no one would bat an eye.
The more questionable are those that assume a different magical framework. I've always had trouble with the Elemental Companion, for instance, even though I did not have a problem with some of the lists (and in fact do use some of the lists from Fire&Ice).
