I feel like seeing the big ass Khazar, Cumania, Pecheng etc. Hordes on the steppe and deciding the focus should be purely on the Mongols is a bit absurd. Like obviously the Mongols are important and I'd love to see them but I feel like at the very least the steppe turkic people should have been considered when making this dlc.
Seljuk-Byzantine war is so weird currently. The Byzantines lose just a bit of territory in the east at best, there's no incursion into and loss of eastern/Central Anatolia at all. Frankly I'm a bit surprised this was not raised as a bigger issue when RtP was in dev.
