Even though in AL the HuD is small and really doesnt bother much in PvP , it can sometimes be the difference between killing and getting killed.
I Suggest having a way to make the Hud more transparent , it would be good even in PvE , i mean who wouldnt want to know their surroundings better. Often in PvP i missed heal packs / manas etc from the HuD , so i think it would be for our benefit to add this option.
