Frosbite wasn't really an issue the first time i played, on the opposite i feeled the weight, i liked the movement flow, to me it haved some great potential.
Good feeling, realism about physics without "manmade tweaks" like Ignite, so Inertia (there's a connexion with what i told), contacts weren't that bad but neeed works, animations looked overally good such as players models, ball physics was a bit too "bullet/bowling" on FIFA 17... I remember some hyper long pass, practically from 40-50 metters without slowing down AT ALL

but it was a collsion bug with the bal. And players was sometimes annyoned by the ball physics.
"Lag" as you call it but due to animations were not that awful, there was some at the launch but many was more due to animations transitions and related to physics... What i prefers in a game than what you're calling responsiveness, some looks to me like a "don"t give a damn about physics", sorry but that how i feel about some games. You could accelerate a bit, but there's limits to me.
Well, Fifa 17, after the second or third patch until the end... It became another game, and all that i kinda liked was toned down in the bad direction.
So i gotted a big problem with Ignite in general, and now with what they've done with Frost, adding some weird algorithm on it...
Fifa 17 gived me fakes hope, because i liked it at first and hated it later.
But whatever, i was like under Division Mode drug, i played it even if the game was super frustrating or i wasn't a fan.
I dumbly played for at least one time win a D1 for the first time (it would have been possible since at least FIFA 11 or 12 but i wasn't aware AT ALL that you could've buy points or extra games on it way before. A mate told me that he won 9 times D1 i was shocked even if he was super good. Now i understand a why, and feel a bit less weak to reached the D1 and lost for 1 point in the others versions hahaha)
