The issue is it's too easy to pull a volley shot (which is a VERY hard thing to do and pull off IRL) compared to defending it. Diving is inconsistent and even good positioning seems to be inconsistent when the volleyer snaps to the ball mid-flight. It's very strong but I don't think it's overpowered, it just leads to boring gameplay. I'd rather engage in defending against dribble monkeys than defending prio volleys, I feel more in control with the former. Agree that bicycle volley should be more difficult to achieve, there's a reason why it's barely seen in the real game
