The Burgundian Inheritance is completely devoid of player agency. Unless the player is Burgundy.
The best countries, outside of HRE revoke strats are (in no particular order):
Mughals
Ottomans
Ming
Yuan
Qing
Europeans need not apply.
Best for what? If you mean for world conquest type games, Qing probably shouldn’t be there. It has amazing ideas, but the fact that you cannot remain a horde on forming Qing makes it seems to be substantially worse than forming Yuan even if it gets off to a bit of a quicker start
Overall:
Austria is clearly the best with HRE vassal swarm, although not nearly as broken as in 1.30.1.
Castille into Spain extremely good as a European, with PUs over Aragon, Portugal, Austria, and England. Yeah, there is now a good chance of losing Naples and Burgundy isn’t guaranteed, but that is offset by Austria being much beefier in basically every game I have played (and Hungary generally being better at resisting the Ottomans so they are bigger when Austria PUs them). The Valencia trade node also can effectively make Seville and end node once you form Spain so you don’t need to worry about Genoa. Spain probably wouldn’t win a world conquest race, but it would probably be one of the most reliable to get it done by 1821 for moderately skilled players.
Timurids into Mughals are as powerful as ever. Probably the best non-horde or HRE option.
Oirat into Yuan got a bit of a hit from razing (the cash early and reduction in MP later) but is still the most powerful horde option. And they have really really benefitted from the TC and governing capacity changes. I find the borders are much better at getting their economies up and running now as they get the extra merchants to drive trade and can get more value out of high autonomy lands. My pick for best outside of Europe.
AI Ottomans are much slower now, but I don’t see why they wouldn’t be their old selves for a human.
In terms of world conquest, the only real change I see in 1.30 is that Austria is much more powerful and the second tier HRE tags are also better, but they aren’t in the league Austria is.
