I already posted this in the MP forum and no response from the SSG team.

Basically creeps still receive Lootbox drops of the new type with no access to black steel keys in the store. If they were allowed to buy the old steel keys, they should be allowed to purchase the new keys for lootboxes correct?? Otherwise please disable the Lootbox drop rate on creepside and allow us to access the same vendor for buffs/Lootbox items that is in the works for the freeps. LBs were always an accessible source for sigils and attack buffs to help out developing players compete.
