Was it really so much easier to defend than to attack?

Personally I believe as long as there is an easy route to one of your cities using a general to resupply is OK.

The traits are supposed to simulate the army's supply status, not the general's. "Resupplying" by bringing in another is somewhat of an exploit. If you however come in with a fresh army to keep up the siege and retreat the previous army along with its general it's fair.

[Gaius Valerius]

the general could be carrying a caravan of supplies with him and women, and booze, ...

I think RTW emulates battles rather well, you march into another factions land, destruction takes place (ie broken supply lines?) this would have forced an army to attack just to keep their economy

[Tiberius Nero]

The only reason it is easier to defend than to attack is that the AI doesn't have the first clue on how to attack decently; they just end up all over the place, come to you exhausted after running half a mile to reach you, charge uphill, don't use ranged units and skirmishers effectively to harass you, etc.
