For lootbox keys to be of interest to creep players, they would first have to have stuff in them that is actually of interest to creep players..... as creep players have no armor, and can't wear cosmetics or ride mounts.... what is there in loot boxes that could be worth paying actual money for?
It's likely that a loot table for creeps doesn't even exist in the new loot boxes.... I guess they could enable a vendor in creep side town that allows spending of motes of enchantment for buff tomes or something or perhaps not drop motes of enchantment, but drop Infamy points instead.... but then the whole pay-2-win thing really comes into play.
I'm not well versed enough with creep side to really make an objective opinion, so I would need to ask:
What is there in loot boxes that would be interesting to creep side, or more importantly: What SHOULD be in them for creep side?
