There's a huge bug that no one seems to be talking about, when you flick the right stick the GK does a running towards the attacker animation when the striker is close, this is easily tested and proven especially with power shots, if the striker is about to take a power shot or any shot my GK will literally start running towards him upon flicking the right stick over and over. Right stick seems to trigger the Y rush animation regardless if you have the rush playstyle or not. You can test this in skill games by flicking the right stick before the shot is taken, this has never ever happened in other fifas and only in this one.
Other issues is the animations are not consistent for GKs, same shots your GK will either choose a great diving animation or flop to the ground or do a bad dive regardless of the timing of your save. So you basically just feel like oh I hope this time my GK chooses a good save animation, up to him. You don't feel like you're in control of anything. Like very easy shots with no power my GK does weird terrible save animations for no reason. The save animations selection needs to be much better and more consistent. If you're a highly rated GK with all the playstyle your GK should start making great saves and the animations need to be much better.
Out of everything OP said, which I agree with it all, the GK positioning is by far the worst thing about playing as a GK. Been like this probably since FIFA 23, something happened to the GK positioning where my GK stands very close to the near post leaving a huge gap for easy goals. Basically if you just hold LB without manually positioning yourself, you're gonna concede a lot, and it shouldn't be this way, manual positioning can never work, it's way too hard and it's impossible to do consistently, LB auto positioning is very important and needs to be fixed.
I truly hope this year GKs are actually better, every other position especially striker has the entire game tailored for them with all kinds of unsaveable shots, the GK is always so weak and broken in every fifa that you spend your days fighting against the terrible inconsistent save animations and bad positioning. GKs are as important if not more than the other positions, and it needs a lot of work, make the strikers and the players actually work hard to score a goal and make it take skill instead of anyone being able to do it so easily because the GKs are so weak.
