Thing is, they are not. These are premium packs, offering you their rarest commodities. You can't really expect a restaurant to serve you a full-course gourmet meal for a couple of bucks, after all.
And they already have "micro" parts in place, allowing you to draw Premium and one of Limited gachas for a mere 1$, once in awhile, and 3$ after that. And even regular draw prices outside of a free gems are not that big at 5$ when you exhaust discounted pulls.
