Hey guys, so I've been playing a Byzantine campaign for a while now and I seem to have hit a brick wall. The goal I set for myself was to reconquer the entire classical Roman Empire and things have been going pretty decent until the mid 1300's. It seems like the AI can just field infinite armies this late in the game. I'm trying to conquer Iberia and can usually take the eastern half of it but after that I can't advance anymore because Portugal can just produce litterally 15 full stacks of halberdiers, pistoliers, men at arms and sword milita. I on the other hand can only field maybe 5 full stacks in Iberia because I need troops on my border with Denmark (who conquered all of Germany), the Fatimids, Hungary and the Kwarmizrians. Basically do you guys have any advice for beating Portugal? General late game advice is also helpful.
