Can you upgreade diplomacy system in Warhammer II TW. I play as Vampires and nobody whant to meake treade deal with me only Manfred. I olmoust distroyed the Raikland, they left with only one province with no army and don't whant to by my vasal or even negotiate peace deal. I have two armys near their last province and win on autoresolve but Raikland behave as autodestructive fanatics and don't even consider a peace deal and vasalization. How to enforce them to agree ? Diplomacy need an upgreate. If fraction is loosing the war it schould akcept peace deals and even beg for it.
