One thing I really hope they get rid of is Super Indivisible/Indestructible China. I hated how in EU3 vanilla, no matter what happened, China never fell into the characteristic divisions and collapses that plague it from time to time. One of the things that sold Magna Mundi for me is that it was very possible for such a thing to happen – I think that one third of my games had China divided into warring states, which I loved to check on from time to time just to see how the mess was going. In fact, that also goes for Russia, Ottoman Empire, England and France, too. They are always united, whole, no long divisions or large-scale civil wars of any sort. They are the EU equivalent of Victoria 2 Super Indivisible Brazil, where, no matter what happens, Brazil never breaks up, ever, it always remains a giant South America blob. Its ridiculous because 1835-1840 was Brazil's darkest hour, it could've split into multiple countries rather than continuing united. Argentina too, which is hilarious because in the early Vicky 2 period it had just come out of a period of instability.
