since i havn't faced off against any greek armies in the campaign or used much heavy cavalry, i gave about a dozen custom battles a shot.

regular hoplites vs legionaire cavalry. the legionaire cavalry doesn't do half bad, but the hoplites hold them, and even won several battles(though they were mauled). taking into account lego cavalry costs about 2x what reg hoplites do, and take 2 turns to train, i'm content with that.

armored hoplites are downright scary though, do a few custom battles with them. i tried everything i could think of short of elephants with laser eyes. lego cavalry didn't get one kill in a few battles, praetorian cavalry couldn't kill more than a half dozen with several charges before they broke. and the parthian cataphracts would be lucky to get a few kills in multiple charges

by no means did i do an exhaustive test, just several custom battles, 1 on 1, no upgrades, and a straight up charge into a phalanx's front. but nobody can convince me that heavy cavalry are some kind of unstoppable rambo's on horseback, cutting through professional spear walls like they were red shirt guys on star trek.
