Bungie is missing something fundamental in their analysis. It looks like they are snooping into everyone's characters and concluding that there is no "core crisis" because many players have a significant amount of cores. But they need a basic economics lesson. Because of the scarcity in the current core economy, players HOARD them. They take so much boring chore grinding to get that players don't want to be caught without an ample supply. And due to the constant increases in power level, players definitely don't feel the need to level up much of their gear to max power since the "goal line" will get moved back in a few weeks. This is why many players just run with one set of armor while the rest sits in the vault.
