Why does Riot not want more possible revenue? (Mystery Skin Related)

Here is a list of the number crunching (I hate doing this usually but it had to be done in this case) of what the Mystery Skin boxes have done over the course of a few days from purchasing them and a good argument price wise and customer satisfaction, or in other words ($$$$$$$$$!?!?!?$$$$$$ ;) )

And so to quote myself at the end:

So why the fudge are we not having Mystery Skin boxes staying in the store or coming back once a month for a few days. This makes me want to give you money for anything possibly other than skins, Riot (Unlike your balance team, but that's neither here nor there). I've literally spent 75+ bucks (RP cards) on (mostly) mystery skins over the past 2 days to get these great ones. If there is anything that has been proven in America's / Human nature, is that people like to gamble to varying degrees even if they consciously state they do not (I know hypocritical, but what in society is not?). Look at PWE, it's a gamble with their lock boxes across their many titles which rakes in more money because of that 'unknown factor'.

Suggestion: Maybe next time throw in the wards as a prize as well? EDIT: Mystery Skin Total Spent / Skin vs Mystery Price is actually: 6370 RP / +390 RP (Favorable)

So I end this this with:

Why. Do. You. Not. Want. More. Money?
