One thing I'd actually hate if BF resynced didn't have

Game settings, control and difficulty customization like Mirage had. If it doesn't have that, it'll be a big issue for me.

I need to customize my controls to the extent I wish and I also need a customizable difficulty.

I want to be able to choose to make the combat hard by buffing enemy damage to 200%, making myself one or two hits away from death AT FULL HEALTH. The combat in AC was always kind of easy. This makes it way more fun. I also want to make the enemy detection the hardest it can be for improved stealth. A set difficulty that I have no control over genuinely sucks.

And, again, customizable controls are essential. A nitpick of mine is that the default control scheme has the sprint button and the parkour button on separate. I combine them for better movement and fluidity. And the default control scheme generally sucked in mirage and shadows. Customization is essential.

Maybe the bar is too low, but it is what it is.
