Well i finally mastered Advanced Shooting after practicing it in training mode.
I also know that i will not be using it. The reason being is that, for me, it is easier to hit the target. I tested this by running away from goal and pressing square which resulted in Kane turning round automatically and shooting towards goal. He didnt score but just means, for me, that is too assisted.
I tried it in my ML CL game and after 30 minutes out of 7 shots i had 6 on target. Plus a goal from Kane who wasnt positioned well at all but he managed to still loop the ball in. I quit the game in the end because it felt like i was cheating.
Don't get me wrong you can get some different shots going in like daisy cutters etc... but its just not for me
