This is the first thing I'll be looking at with the move to Frostbite. If line play still greatly resembles the same stuff then it's going to be a huge disappointment. With the way Clint talks about what it would take doesn't instill much confidence in me that it's coming any time soon but we shall see.
The booth review video is one of those where you have to think about the other side and the problems it could cause. The worst issues I've seen with reviews are those which is shown where the WR catches and as soon the receiver has two feet down it's ruled a catch so what the review is basing it off is actually correct, the rule in the game isn't representing the huge gray area of what constitutes a catch.
Agree with this but with the emphasis on MUT and eSports I just don't see it happening. Like with what he mentioned about Russell Wilson getting stepped on falls into the same category as the fumbled snaps and QB inaccuracy where the competitive side will just simply never embrace it which I think makes it highly unlikely we'll see it implemented. If we do end up getting a Sim vs. Comp settings separation then those things should definitely be things that are options provided somewhere down the line.
The main thing with this topic though that I'd add is the canned/scripted events that occur. Most notably the blocked kicks and those animations like the WR/DB one where the ball would get deflected out. It's inorganic and completely destroys immersion in those scenarios. They're things that are great to see for the first time but then once you see them over and over again, just make the game feel stale and elementary.
