Every 22 hours you get 100 Mist Energy.
That's around 395 cycles a year.
So... 39,500 ME every year.
That energy would be worth about $100 to buy.
You get that every year.
By paying for another account to give it a separate Mist Energy reserve, you're getting an added value of $100.
So $200 a year. Or about $16 a month.
The equivalent of a subscription fee to a game.

It's paying you to play.
Well, that can't really be true. The refill of mist energy was something put into the game that has it's cost paid for. The amount of ME used each and everyday doesn't result in any form of money, or at least I think so. But the CE and other real money that we pay is of course funding the Devs for more updates and new ideas to put into the game. I'm pretty sure mostly everyone knows this. It's business and every company needs money from the users to make updates for us.
