Darkest Hour was my first paradox game ever, I really liked it, and then I played HOI3, and never looked back.
HOI4 should be iterative and include the best of both worlds. I suspect the necessity for micromanagement (which I don't mind, and some others don't mind) will be lessened, though - it's a barrier to more people playing the game. I'd prefer if the option remained to give orders to every division, but I won't be crushed if the emphasis is on high-level strategy. But yes, more decisions - learn from the popular mods for HOI3.
