The first point would be quite a problem, and your second point is why you cannot ask your Spellcasters to target a specific kind of units. ( Mages would also target Mages, leading in an artillery battle) There is also a third point, tactical combat would be impossible in PBEM against other players.
I admit I would rather see a working auto-combat feature without tactical combat instead of tactical combat but virtually no Fast Combat/Strategic Combat or other names. (Like in AOW for instance)
As I wrote in my earliest (below I believe) post, I would like to see improvements to the combat replay feature though. I have a lot of problems to see what is going on, but according to the screenshots, the representation of the battles has changed quite a lot.
Edited because of my silliness.
