Why does the "Revel Red Envelope" cost 55 more RP than the Chest+Key combo?

I can understand why you can't use the personal shop we all know and love if the technology just isn't there. But if you're going to go this route, why are these things more expensive than the chest and key combo? That's basically all they are; buy 4 chests and have a chance to get one free. The Envelope is 250 RP yet a chest/key combo is 195. If you open 4 chests and manage to get four gauntlet relics, a one-in-three chance for every envelope, you get a free skin! However, buying four chests would cost 780 RP. Buying 4 envelopes? 1,000 RP.

You're... like, stealing money from us? How is that any way to treat your loyal players? I totally understand we have no right to complain about optional events. You have to make money, I get that. But how can you hide this behind cute trinkets, relics, and a Lunar Revel event? It honestly feels like you're trying to trick us into spending more money for less product.

Yes, I know you can trade 3 relics into a chest/key combo. So in that absolute base case scenario, you save 30 RP. Which is pennies. Worst case scenario, someone blows 3k RP trying to get a random skin permanent. This "event" shouldn't even be a thing. It's so gross. At least the snowdown version of this had themes that changed everyday and offered cute in-game interactions. You're not even trying anymore.
