I do think 45 degree angle timed finesses may need a tweak, but there are ways to combat them as manually shifting your keeper even slightly is enough to stop them if you time it right - but in my opinion they can't do anything to finesse shots until they've made other more important changes. Timed Finesses are one of the few reliable ways to score this FIFA, as if you're able to get a bit of space on the edge of the 18 yard box they you've a decent chance at a goal. Until they tone down AI defending and or improve passing intricate play around the edge of the box is dead, so its either lump it in for a cross or try and finesse. If you smash finesse shots without other tweaks first then there are fewer ways to stick the ball in the back of the net, and that isn't fun.
