Dear dmg04, The problem around cores is quite simple. They have no place in infusion. Infusion is a way of just progressing your character to max level, this is basic character progression and therefore should not limited by a material which in it's very nature is scarce. The reason why they are scarce is due to masterworking which is an end game activity made to perfect your build & loadout. You can not tie a basic character progression system to an end game currency. This is contradictory in itself. You need to stop with this. Take them out of infusion or make them a common currency like shards. But doing so will devaluate end game masterworking. There is a great opportunity here if you take them out of infusion and expand on the end game masterworking. Allow perks to be rerolled once masterworked, both on armour and weapons. Allow us to change between mobility, res & recovery. Allow us to go from a normal perk to an enhanced version. Keep cores for those kind of things. Allow us to perfect our gear to our liking this way. Then the scarcity of the currency is warranted. Now it's just contradictory. Why can't Bungie see this? It's clear as day. I know there are a few members of the community okay with the current system but I can guarantee that when you change to a system suggested above your entire community can get behind it. I can't imagine a single player not wanting to reroll perks for their beloved items to perfect their loadout or augment to enhanced versions.
