The change to the new gear progression necessitated we go back and update all our loot box products. We viewed this as an opportunity to standardize the contents of these boxes and our hope is the enchanting materials contained within them will provide similar, if not increased, utility over the old boxes. I can also confirm, as some have already alluded to, that this transition did not negatively impact the chance to earn the jackpot item from any one loot box. We simply replaced those items that were no longer relevant to include and left the jackpot product untouched. We felt this was only fair to existing owners of these boxes (players that might have existing loot boxes in their inventory or Item Claim).
