Normally id agree with you, but the caesors legion lacks any real area of effects (they do have some better armour and flame throwers [woot] though)
But, in an all out war, everything vs everything. Augmented weapons from the best of the mages, and all the militia the towns can muster, as well as the soldiers that can be contributed by the legion (and the fighters guild) would make a difference. Especially considering caesars legion, EVERYTHING, is military. they can't muster anything more then what they have, besides tearing down their meager shacks to build a palisade.
Id really preffer caesar to win, but in all seriousness, I just don't see how
