No comment on the fact that he set up his empire for a collapse through civil war because he was unwilling to consider the future? I figure there's a decent chance that there would be centuries of Macedonian hegemony if Alexander did the very bare minimum in that department. If he had simply wrote a will at any point that read "Ptolemy is in charge if I die with no heirs", we might be arguing about Alexander's place in the pantheon of great Macedonian Emperors. I would never claim that Alexander wasn't a great commander. But he had the road paved by his father, and the empire collapsed like a decade after he took the throne.
