Thing is, Bannerlord has lost a lot of what made Warband good in the first place to begin with, largely by responding to suggestions (so it seems) that the campaign should play out more like Crusader Kings. They've completely ruined the progression system, which is an absolute joke, and the only real change they made to diplomacy was a straight downgrade in the form of the Influence system, which you yourself want to jettison which I can only imagine was inspired by the similar magical generation-spanning currencies in Crusader Kings II. Mount and Blade, at its heart, was an action RPG. Strategic elements were, and should be, secondary to all other concerns. With Bannerlord they have apparently tried their hardest to cut out or simplify the RPG portion to the point of irrelevance, a criminal mistake in my opinion.
