I'm not aware of the consumables on the package, I only knew that it contains armor set and accessories. If it's giving ice roses for like 1k pieces, I understand the purchase limitations. But if it's not that much, I don't think anyone would be foolish enough to spend that money for a pack with redundant items with little to gain.
Imo, some of the purchase limitation doesn't make sense like you have mentioned about HEWR.
Imagine if that's the goal for ncoin purchase, wouldn't make more sense to not limit the purchase since the money that it's going to the game will be higher; that's more income to the company, right?
