I have adjusted hotspots. I get a good amount of 3pt shots as well, but they are usually open looks through a play, or shooters spotting up in the corner. My goal is to get the game to be dynamic in regards to when a player would pull up from 3.
As for Melo, I don't have HIS midrange and 3pt at 100, I have the game sliders at 100 for each. His mid range and 3pt are at 50 in my roster.
