This is really the only problem with DeI. I'm a veteran, but Carthage especially DESPERATELY needs a Rome-style script, or better several of them, that spawns full stacks periodically when they're at war. The AI cannot handle having a spread out empire in Africa, Sicily and Sardinia. Egypt and the Seleucids at least build armies even if they use them badly, but the epic struggle I want against them as Syracuse is just completely absent. They're utterly inert.
Dresden, I beg you, adiuvame, o amice!
