The mod didn't break any major country (other than Burgundy). Not superblob well, but they're very formidable.
Vijayanagar is the closest to good old blob, I don't really know how it compared to vanilla EU4 since I never played in India.Ottomans got beaten by Orthodox minors somehow almost completely out of Europe, with Byzantine Greece recovering (probably mostly thanks to rebels).Poland got into (random, but likely) scripted union with Lithuania and they expanded a bit, but nothing extreme.If keeping it alive long term was the goal, then it still failed, but at least without any scripted events.Everyone ganged up upon Burgundy - France, England, Emperor, variety of HRE minors (who are now stronger), and Dutch rebels - until it disappeared completely in 1490s. Maybe it should become part of HRE like in EU3?.Hundred Years War continues every time truce breaks, with either side winning a province sometimes.
