[b]Old name:[/b] Masterwork cores are for masterworking armour and weapons not infusion and should be removed from general infusion its not needed!!! [b]New name:[/b] Enhancement cores are for enhancing armour and weapons not infusion and should be removed from general infusion its not needed!!! Yeah changing the name has made it less confusing and made it clear what they are for!! Silly names aside by adding more sources to get these its made the whole system pointless Bungie said they wanted people to think about how they infuse and make it a costly decision however when you hit 600 like I did a few weeks back you will find that cores are not needed as much and steadly start to build up adding more sources means I can go ahead and just enhance everything without a second thought if they removed cores from general infusion but kept the drop rate the same and did not add more sources then I would need to actually pick and choose more carefully what I use them on.
