You are spot on about the ball trajectory and speed, although, about the speed, i donīt know if itīs the ball going slowly or the fact that it misses that blur we are used to see in the real world.
Anyway, i can live with the speed issue, but the trajectory thing kills the imersion a bit. I remember seeing the same issue in past FIFAīs (much less in 16, but very present before that), in crosses specially. If we cross from the right side for example, with the right foot, the ball usually does this trajectory ) yes, this is parenthesis, just to exemplify what the ball does in the situation describe. But sometimes in FIFA, at the midway point of that trajectory, the ball goes to the other side, like, if the wind caught it!
Donīt know if im explaining this well enough...
