To my understanding, the Corps level and OOB as a whole are removed to reduce micro-managment. AI do not ultilise the OOB and cause a hell of a mess. As a player, the Corps level require the HQ unit close to the divisions and when the war starts, it becomes a click-fest.
PS: I do like to somewhat have a abstracted OOB like Field Marshall > Generals > Div compare to the current version of FM and General role, while the current Theater > Army > Div is fine with me.
