I wasn't fast either... Got to around 440 or so.
The blasted Western Empire sank two fleets full of elite armies when I sent them to take Carthage. The first one was rather weak and I tried to sneak it along Africa. Didn't work as it was sunk just beofre it was suppoed to unload. THe next one got a powerful fleet and strong escort (other fleets) but the WRE seperated it from the escorts and sank it too. They nearly managed to do the same with the third fleet.
The worst part was that the first two fleets came from Antioch and the last had large sections from it too.
