I had been waiting for patch before I started my franchise as well. I played a bunch of play now games and then my 3rd CFM preseason game a million times so as to set my sliders and decide yeah or nay on X Factor. The "crouching linebacker-hidden swat ball mechanic" showed itself pretty glaringly. Even when clicking on to a defender and attempting a user swat, the animation does not trigger. Every other input is working in the game, better and more responsive than ever.
You said it best; the ball trajectories being reworked as they've been are enough. They nailed that as well as they possible could have.
Just give an "underneath defender" a chance to make a play on the ball only within his reach.
If I don't put air under the ball when necessary, I want to and should pay the consequences. Now that I've been given that tool, it's on me to use it and not receive any additional boost. I would add that on a real short-quick throw, if the LB doesn't have eyes on the ball coming, I can see him then not being able to make a play on the ball in that particular situation. Just needs some fine tuning. It's really close. Nothing crazy.
