Isn't it because the fact that when items are put on the featured auctions, since they're limited in supply they are monopolised by the rich community? The supply depot gives everyone equal chance to get what they want without having to pay massive monetary markups through multiple middle-men.
Or are you pointing to the fact that only now people are getting edgy about BKCs being added to supply depot when the featured auctions have been around since 1942, last wednesday?
I'm not sure...because if this goes in the supply depot, then it'll make all the other Kat helmets pretty much useless. Also if OOO's aren't making as much money then I'm not surprised. They stopped the explorers pack, we got free elevators. Sure they've brought back loads of players because of it, but I personally thought that OOO's was going to make a loss on it.
I think that it would be a possibility if they add these Bombmasks:
Shocking Bombhead Mask
Fiery Bombhead Mask
Frosty Bombhead Mask
Lovely Bombhead Mask
Toxic Bombhead Mask
Cursed Bombhead Mask
Checkered Bombhead Mask
Scary Bombhead Mask
Starry Bombhead Mask
Magic Bombhead Mask
I'm not sure on the Black Kat Cowl though...It might be possible.
