Yes, this is the exact reason I use L2 on crosses and lob. On lob passes, it's too long without L2. On crosses on penalty box, I can't do short cross when my passer is near the 6 yard box. On the flanks, I feel like I have no control on the length. Direction wise, I agree with you. I just tap it. It's mostly around 25-35% power but I really don't think about the power when I head, I just think of tapping it. I'm like the same but I feel it's more than 70% chance they'll make an effort to head(Maybe it's lower, not sure) . I always try to target my cross/pass in front(towards the goal) of the player I wanted to head. I still feel I'm not 100% in control on open play headers, I feel I still need some luck. It feels better when I score volleys instead of headers. It feels more like I did it than the game helping me score if I volley.
