Are the Romans too Powerful?

[guineawolf]

I am running vanilla RTW at 1.5. To compare the troop qualities of the Greeks and the Romans I created a custom battle with one army of only Spartan hoplites, all upgraded veterans, and another army of Roman troops, all of which were Legionary 1st Cohorts, upgraded to the max. The Spartans were defending an unwalled minor city, sort of like Sparta in the 'Siege of Sparta' historical battle. According to their unit card description, they are 'perfect soldiers'. However, in reality, they were massacred to the last man by my endless waves of Roman legionnaires, even when I set the difficulty to the highest possible level. Even though this was not really a formal, scientific, closed-system no-variable experiment, the fact that these Roman legionnaires could basically chew up and spit out the very, very, very, very best the Greek cities can offer chills me. Does anyone else recognize this problem?

do you ever noticed your spartan's stamina?
when both side stamina reduce to lowest level,that it will lower their attack and defense "skill"=combat effecientcy,but not their armor value.....
roman legion=12 armor
spartan hoplite=3 armor

i only figure out a way that read in roman history,when using phalanxe for defense,try using some rotation method,that will conserve their stamina,like first line unit fall back behind second line unit after receive first wave of attack for resting,then when the second line unit fall back behind first line unit,those first line units oredi become fresh again,and so on ......
