In my last game the German Empire conquered the entirety of Egypt state by state over a couple of decades until they had the whole thing, but historically Britain’s conquest of Egypt looked more like subjugating them as a protectorate.
Yes Egypt also seems like a place where weird borders are created. In the same run, Britain directly controlled Sinai and the Provinces on the coast from Lower to Upper Egypt, but also had the rest of Egypt as a puppet. And i think that shouldn't happen. I actually like the Great Powers fighting over Egypt, it is a valuable region, it makes sense. But it should be more about extracting resources and wealth rather than about directly governing a population.
I mean I also wouldn't mind if GB on occasion would carve out at part of China and made like a "south china protectorate" or smth. But the direct ownership of states goes too far imho. It also makes taking these states away from Britain almost impossible. Because there aren't any large country tags for china you could release, most have 1 state, many states don't have any way to release them and taking them from Britain would generate 4x the infamy that Britain generated taking them.
If you actually want to break Britain currently, the best strategy is probably to conquer China yourself so Britain can't get in, which feels kinda stupid. But I feel like there is no other way. In my run in one war I took over India and released Ireland, Scotland and Wales, which I thought should be absolutely crippling, but it took the British about 7 years to be back at the same GDP they had before our war. Losing Canada and Australia and the larger African colonies later barely even put a dent in their GDP. At the end of the game the only British owned English state was Cornwall and they were still the #6 great power having a GDP of over 200M.
I remember in previous versions of the game Great Powers always wanted to put treaty ports everywhere, and now with all the changes, where you would expect that treaty ports are more valuable GPs seem to think "why take port, when you can take whole state/country?"
Also maybe secession movements should be stronger. They hardly ever rebel and even when they do they are more annoyance than threat, but a secession in a far away land with millions of people should have a serious chance of pushing out occupiers, no matter how far behind they are in tech. I mean even the Zulu won some battles against the British (even though they ultimately lost) and they were fighting with Spears and Shields against Guns and Cannons
