Even using cam properly could be trained imo. Since I've been in D I start to use my right stick to know where opponents are, where they're facing and how much space is available for the best play I have in my mind. At the beginning It was only use back view by clicking the stick, then I realize that quite often, just by turning camera left or right gave me the infos I was looking for, with less loss of vision of the field and the current play, gaining small amounts of time that could be crucial. Hope It helps :)
