I will borrow my posts about culture change from the 1257 Mod. I hope an option is present to switch cultures in captured lands. That is the only solution I see. Logically there is no historically accurate way to deal with this.
"I will make one more point about troops in different regions/cultures: When I took Barrca in North Africa, I was subsequently at war with the Mamluks. The thing was I was fighting their armies with the exact same troops as they had. That is what kills it for me; a carbon copy battle, with forces the exact same as mine just seems out of place. I am essentially Mamluk, without a culture change one completely adapts to the culture you conquer, which is historically inaccurate. There is no conquering, it is about adaptation. The passage of time on these big mods like 1275 and 1200 is not really relevant. "
