I only scout at D3 if I really want to know if a certain attribute is low-high or high-high. Let's say there is a SG with a 40 PER and I like his SPD/DEF/P/BH/WE. If he is low-high, then I am lukewarm on him and he is a backup option if I can't find someone better. If he is high-high, then I will go after him.
