I have 300 cores and I have 5 sets of masterworked armor and 40+ masterworked weapons. No exploits either. Check my game history when the exploit was active. Wasn't even online. We may be the minority, but there are a lot of players in my position. Bungie, if you completely remove cores from infusion, they need to have more functions. Maybe functions like rerolling masterworks, change 1 perk per gun at Banshee, buy certain consumables (maybe ones called something like "Hand Cannon Telemetry" which will increase the drop rate of hand cannons from all sources), re-rolling weapons entirely (with some sort of limitation of course), changing the appearance of one piece of armor to that of another, etc.
