I think people place too much importance on Antigonos' Army in southern Greece.

You could easily hold all of southern Greece by turn 4 in .82.

Antigonos (almost) always went north to fend off Phyrrus. If the Epeirote King still threatens Makedonia Proper from turn 1, he probably does this in 1.0 as well.

Although, I'm not sure of the KH make-up in the beginning, so I hope it isn't possible to blitz Corinth and Chalkis by turn 3 anymore.

In my humble opinion, the KH should have the feeling of being on the edge of annihilation in the early game, as the Chremonidean League was never really in a position to build a pan-hellenic empire.
