Well if you're going to continue with the enhancement cores impacting casual players equipment choices because we all know that it does not affect hardcore players equipment choices or even slow them down a little from reaching Max light. As I ran into several players that were already mid 690s with fully masterworked new armor and weapons the first weekend of the DLC drop. enhancement cores need to drop as you play the game not be a separate chore or distraction from the game from the game. And have a high enough probability to get a core after an event(heroic public event, crucible, strikes, story missions, raids, extra) as in RNGesus doesn't love everybody to same. So in summary, receive enhancement cores as we play the game not separate time wasting missions.
