Rinse and repeat. Just as one can solo the Vault glitch and farm materials from the first chest, we will all be trekking to the first chest at the bottom of the Hellmouth because that free chest will give Radiant materials as well as Exotics from the new loot pool. It's just slow to accumulate, but the only way to get to Level 32. Considering my Ammo Bullies clan-mate picked up a Dragons Breath from this chest this very week I think we are all going to swing by regularly.
