Yes they fixed manual headers.. I am a full manual player, and often use the L2 aimer when heading, and Ive now scored 3 headers in total. None of those ballooned ones yet.. which is good..but I do think the ballooning should happen if you mistime the header. In regards to headers... and this time, not on goal, but whilst getting up during a goal kick, I find my player (particularly) a tall one, gets the head to the ball so much easier than pre-patch. Gives me more control which I love. In the past, id get frozen and not even go for a header (after pressing the square or x button) even if in front of a player. Great they fixed this. Just makes me feel more and more in control.
Only thing I haven't really tested is the r2 finesse shot via full manual shooting. This has been broken since 16 I think (sure it worked well in 15). You'd aim (even using the L2 aimer) at the corner of the goal, but the ball would often start so much wider than where you were aiming, and not even get close to bending back to where you wanted the ball. you'd practically have to aim at the keeper, straight at goal, to have it go into the left or right corner. Ill try in training....
