Ok.. did a custom battle twice against the same type of Spartan army but this time giving them as a full stack of units (no elite hoplites though)
In both custom battles the Spartan's were harder to beat than in the campaign game - I couldn;t break them as easily, and 2-3 of my own units routed in both battles. Both battles lasted 15-20 mins compared to what seemd like 5 mins in the campaign. More kills made by the spartan's in both battles - compare that to the campaign game where they only inflicted 49 kills.
Spartan Army - similar mix of unit types with same level of experience as in the campaign. No armour upgrades.
Custom Battle one: I made a mistake with my macedon army in battle 1 - 3 too many cretan archers, when in the campaign it was 2 greek archers (+2 exp) + 1 cretan archer.
Custom Battle 2 - Modified my Macdeon army to match the one in the campaign
Here's the results from a battle in the first campaign against 4 different spartan armies in 2 battles - all very small but look at the kills that they were making and compare that with now:
They are still in my opnion too easy to beat in the custom game with the mix of units that I chose and what the AI seems to be picking in the current Mac campaign.
