I can confirm that trade do need to be nerfed a bit, I was making 500 ducats out of trade with england in the 1750`s, thats without production(125) tax(40) tariffs(100) and gold (30), having over 125 heavy ships 120k army level 3 advisor everywhere, 15 subsidies to newfoundland, thirdteen colonies , british west indies, british colombia and australia, and funding rebels at a few places, and yet I still make over 120 everymonths (while mothballing my fleet though) lets just say that scores place me first by a large margin on every category, I do believe england needed a buff and france a nerf but this is too much, I have triple the fleet limit of the 4th next combined naval powers in the game and the 2nd biggest army in europe.. and about quadruple the income of a somewhat strong and untouched france
being at war only slighty reduce trade because england is such a naval power it can take on a coalition of the 4th biggest naval power and still only lose a few ships and trade power, and when you have over 20000 ducats and nowhere to spend them its quite easy
oh by the way this with an england who hasnt left the british island except for obvious colonial area and india and hasnt took dutch and french provinces in english trade node
