“Please give finally for the Hero Vlad Dracula his own Vlach/Wallachian civ to the game.”
The developers have already created the Coat of arms for the Vlach/Wallachian civ at the Definitive edition from 2019. All that, what is missing now, is the addition of these civ to the game… It was a similar thing with the introduction of the Poles and Bohemians, so you can do that in the same way with the Vlachs too. I see no reason against it.
