have all the weapons i want masterworked, dont care much about the armor. i have 154 cores left. i really dont know what to do with them until my characters are all 700. i have 3 power builds on my Hunter all running 10 Res over Arc, Solar, and Void (PVE) 18 "stacks" that was fun to get the armor i want to sync with the weapons i use. - they dont belong in infusion they should give you the ability to enhance your weapons - such as RE ROLL THEM!
