I came to CMx2 from CC too, and I had a hard time adapting to it, but I'm so very happy I did.
I'm not a big fan of CC5 strategic layout, since it doesn't create realistic battles or tactical/strategical behaviour, specially because the AI is not good playing the battles having in mind strategic objetives (actually it isn't good playing at all). Achtung Panzer Krakhov 43, my other favourite tactical game, has the same flaw. I don't think that there's any game that offers an operational layout consistent with the tactical battles which is both enjoyable, realistic and manageable by the AI. And I dont think it's going to happen in a near future.
But actually I'm not worried about that. I love branched campaigns in which your actions have an impact in what happens. CM2 already has that. CC2 was awesome in that regard, it was not totally scripted as you wrote, but brilliantly designed so that the events on every portion of the theatre had consequences in the development of the campaign. Besides, you could allocate resources and focus in what you considered important. I'd love that CMx2 campaign engine could evolve and create a similar experience.
