The two biggest overall improvements I've seen since the league started are the kicking and tactics. Season one saw so many players grab it and basically try to boot it forward into space, with some pretty terrible results at times.
I agree that these aspects have transformed the women's game.
Another one for me is the ability of players to dispose of the ball when under pressure or being tackled. Early days, the tackling intensity in the game far outweighed the ability of players to get a kick or handball away, or to break free or evade, but the balance feels much more even now.
