Kronos I believe you misread what cow wrote lol.

I have found that unlike rtw, the spearmen play a more crucial role on the outskirt of your main force. They can be used to intimidate enemy cavalry or if they are foolish enough they will try and charge them. If you attack their cavalry with even weak spearmen will usually take the battle.

I've noticed alot of Archer units, particularly in the Byzantines and Muslim factions have strong melee and defense, so you can use them as archers then double them up as infantry when the melee engages. Be careful, though because they may be tired and could route fast causing a morale penalty. It might be a good idea to use them to flank or stand near the melee bout to offer morale bonus for numbers/flanks being covered.

Don't make your general an archer/artiller/anything easily routed.

Take notice to the small details such as armor piercing ability and stronger armor types. Sometimes these are not listed in the descriptions so you have to guess, most likely late units have more defense due to armor than early units. You can sometimes tell by their appearance though this is not reliable yet since we do not have the info unpacked *shakes fist at cow* Units using maces and Axes usually have armor piercing, and check what secondary units cavalry have, because they might have a mace (Cataphracts were great for this in RTW).

Hope some helped, PS Cow im gonna msg you on msn for a proposition.
