So when DE made this power Toggleable, they didn't change the Affinity Points/XP you receive per use of it. Because it was originally a 75-Energy Power, you still get 75 XP every time you toggle it for 10-ish Energy. If you have a controller with a rapid-fire feature, you can just tape down the Power 3 button after clearing out an Extermination mission and leave your computer running overnight - free leveling for any of your low-leveled gear.
