For all of its advantages, France is surprisingly tricky to play, and 1.8 made it trickier: France starts with a bunch of vassals eating up dip slots, and local autonomy means that integrating vassals makes you weaker in the short-mid term. Add that France is surrounded by great powers that hate its guts. Not exactly a hard start in the grand scheme of things, but there are easier and/or more straightforward starts available. On paper, France is the most powerful nation in the game, so the temptation is to go nuts crushing your neighbors from the first moment, but that's unlikely to end well unless you're an experienced player.
The only problem comes when you are new and try to set untenable goals. You can get obliterated, lose vassals, lose cores, and still be a colonial powerhouse. I guess there is this strong sentiment for many people that losing cannot be an option, but for a few countries (france and ottomans) you can get flattened and still play the game, unless the idea that you aren't dominating is a problem in itself. You have to really try, like, give away concessions in separate peace and the like, to get knocked out. Your vassals should be able to independently win wars against anyone but Austria, Burgundy, Castille, or a coalition. If you simply don't fight any of these, even if it means progress is slow or someone you REALLY wanted like Provence is off the table... oh well! I was under the impression that if your army is intact and standing, and your manpower is fine, the ai doesn't attack you - you look too strong. If you do get attacked, just lose. It's not the end of the game!
I don't see how there are too many easier starts. Ottomans, Castile, maybe Poland?
