Pretty much any settings on map with >1000 territories is gonna be hot garbage.
Hot take right there
Could you at least give me ideas on what i should do instead if what i should not do?
Dunno man, just test it yourself, see if it plays out like you think it does (maybe have a test game first) and then adjust if it doesn't. It's hard to tell whether it accomplishes your specific goals. That's what you have to know yourself, what you want to do, and whether it works.
