The base idea of specialist was if you wanted a cul at level 60 and no other crafter so you could make raid food that was what it was for. But then you had to buy the skills and they were not better that omni crafting skills. So they failed twice there. Then they doubled down with locking certain things behind specialist so only some could make it ok fine but they still didn't fix the original intent of one crafter with special skills to craft with. What ever they do they should find their way back to if you only want one crafter, give them skills that omni crafters have and don't make them pay for it. Sadly i think they may just make it more complex but we will see in time.
