In my current Burgundy game, I've been emperor for a long time (it's around 1660 now). I have passed all but the last 2 reforms. I have gathered 100 IA.
There are 60 HRE members atm, of which I have vassalised 35 if I counted correctly, and 45 are allies. I assumed that would allow me to pass all reforms without trouble, but it seems it doesn't. I revoke the privilegia, but all that happens is I lose 50 of my 100 IA.
What kind of relations are recommended to have with the vassalised/allied members? just positive doesn't cut it I think, should I bribe everything to 100? 200?
