Pardon me for digging out my own thread from the tomb after all these years. I am now playing another VH/VH campaign of m2tw vanilla. Again I have conquered the entire map already but this time I have allied with Papal State and have left HRE alive and made it my vassal. Still my reputation dropped from “immaculate” to “very trustworthy” at 68th turn. I wonder how many allies do I need to neutralise the negative effect of global normalisation of reputation under VH difficulty.
