Actually, France could use a center of trade in Paris, since ATM getting trade power in Champagne is impossible without conquering half of Europe.
Haha yeah, when i checked my trade nodes when i first played as france with the new set up i thought "and this is why i've an excuse to conquer half europe...."
Anyways france in this patch is fine and as an england player you could even win the war without dropping your armies. England armies are also supposed to be very weak once that france's Elàn kicks in. Austria and Castille have had a moral bonus boost to their traditions some patches ago so that they can still manage to survive when france has Elàn, since they're gonna be around france (most times ofc) much more time than england. So, dowing war to france as england not early is very unwise since for 1500s france shouldn't represent a menace to you anymore instead of a blob that has got all the time to grow stronger and stronger. If you wish to do so then you should get some Military idea sets and still think that you're handicapped because france for sure will do the same and have higher bonuses than you in the end. It's also a lucky nation in ironman so that it's even stronger than its real weight, and is supposed to have godly generals if it has time to wage and win wars, which you gave to them. That + offensive and lucky nation bonuses will make you always see at least 2 stars generals deployed on the ground. Also, against enemies which have the quality of france is mandatory to consolidate armies and follow the best ratios, reinforce while you get attacked and try to defend only, using mountains, hills, or rivers. I usually use the tactic to drop 18k on caux and dow france, wait france to come into caux (which at least has a river), and then reinforce with other 18k with navies. If you manage to do things quickly (not using the automatic transport and loading the armies manually) you'll able to transport armies from england to france in 3 days and make the AI calculation of nearby enemies go nuts and win easily the battle because france thought you just had 18k on the continent. This is an example of a gamey use of transports and this is why wiz will always be right when he says that human cheats way more than AI does, and that's why actually nations are balanced around other AIs and not around the player since he basically can do what he wants.
Also keep in mind that when you'll delete france the game will be downhill and boring, they're supposed to be the strongest nation in europe in this period after all.
