I very much enjoyed my 0.80 Casse campaign.
It took about six tries before I found the right profile for the initial build up, I had several attempts at expanding from the start - all massacres. Then a couple more losses from going too long with minimal army and getting stomped on by the wandering Euletheroi stack.
At no point was the conquest of Brittania easy, even though I was getting stronger after every capture.
Then I was faced with getting over the Channel. I lost several complete fleets before I found a fleet size that would last long enough to get a stack over to Armorica. Even then it felt like smuggling runs... hang around too long and the Pirate train arrives and pounds you like a trip-hammer until there's nothing left afloat.
Once on the continent I subsisted mostly on a diet of levies from captured towns, and mercenaries, with the occasional stack of elites from Brittania (when the Pirates weren't around).
In 0.81 it sounds like it might be even more difficult for the Casse on the continent - I relied heavily on mercenary Gesaetai (who have apparently now got religion and given up hiring themselves out). I was appalled how quickly my own elites (Calawari) died - I ended up using them mostly as cheerleaders to encourage the levies.
As for chariot generals - what hot-house flowers they are, I could swear that some of them died without any contact with the enemy at all! (Of course Brittania is famous for the virulence of its Common Cold.)
