Just look at this:
This is every game, either all of this is red or its green, there is never variation, its just a block of factions against the HRE faction, once it gets mauled, you have one enormous blob. There are no sub mods or methods I found that fix it, except the crazy ones that turn the AI aggression into pandemonium, but nothing with nuance or finesse to make the German/Italian factions have some variation in diplomatic relations.
Basically its impossible to get any fun in the western part of the map, usually the HRE are good with England, so after France gets eaten up you almost get the ing NATO... I just don't get why does it take a year or more to fix stuff like this, other mods have smaller updates to rectify stuff like this.
