Surprising level of transparency here when it’s very easy to just ignore these kinds of questions, even if it’s a bit roundabout.

“[W]e have to take into account numerous factors to make sure that boosters packs are equally desirable. One of the biggest factors is the overall average powerful level of the cards.”

Translation: no one would (theoretically) buy “under-powered” Standard boosters if they were the same price as “high-powered” masters boosters. This doesn’t really appreciate players who want to draft or want Standard cards (and would therefore buy Standard packs regardless) but I’m sure they have people there doing this all day every day.
