Or at least they're far from intuitive.
I just had a little bash-your-head with Denmark (leader of a PU with Sweden AND Norway..fun...and of course the HREmperor did shit..that doesn't sound WAI, not by a long stretch of the imagination) and wanted to concede defeat, by swearing fealty to them (they wanted to annex Lübeck). Turns out, no matter what I chose (Denmark gets Lübeck; Denmark gets Lübeck AND I'm becoming the vassal; I just become their vassal) it was unacceptable for them. I don't think that this is how it works or how it should work or how it was intended to work, otherwise we could just throw the whole diplomacy shit over board and do a Total War style "Gotte conquer 'em all". Puuuuhlease tell me this is not working as intended.
