For even access, I don't think European GPs or countries with similar development have it easier than Asians/Africans. There are plenty of locations (Shirvan/Kazan) to move the capital to.
CNs won't make that much difference, Mexico and California are the only ones you can feed to the trade chain, but it's definitely worth building manufactories in those two. You can check what is your current trade value multiplier. Trade efficiency also looks a bit lower then typical for that time, I think. Combining this with missing manufactoring in China, Girin, Nippon etc probably explains the low trade income. But that's true that after a certain point income becomes sufficient for practical purposes anyway.I have a lot in India but not in other parts of Asia. I suspect that bigger CNs with manufactories are also needed to reach that level of income. I know 10k isn't farfetched since smaller European starts can reach those levels with minimum blobbing. Income isn't too important after a certain point during WCs but I was surprised I could only get to 2k even after rearranging merchants.
I agree that TCs work in a strange way, however Indian tags are in an excellent position to take advantage of TC - they can easily move the capital to Africa (and later to Oceania and Europe) and they can start taking advantage of TC right from the start. It's a bit harder for European nations to get there - most will likely need to take Exploration first.My problem, or my concern is basically this: TCs are ultimately responsible for more of my income than states. I stopped even making states a while back because I simply have all the money and FL I could ever need and MP are far more scarce in the late stages of a WC. The reason that is a problem is the uneven access to TC land depending on where your capital is. I quite like the suggestion of changing the restriction from continent to sub-continent. That still massively screws Indian tags over, although maybe the ability to get perma-claims on that entire sub-continent sort of makes up for it. India is my second favourite place to play after Western Europe and I was thinking about a Vijayanagar game after I wrap up this WC but I'm put off by realising that France is a better tag to play an India-focused game.
