The spartiates and kings guard are the only proper Spartan units, some of the athenians and all greek elite hoplites are not as good as them but should be better that the Spartan units that are not Spartan
Equals. I have used similar or the same attacks are they all had the same spears and it allowed me to balance things by defence stats ~ which is what then makes one units stronger than another by armour types and training etc.
We will look into the balancing tho.
