What is Celestia's rationale for releasing Discord?

[RoseLaflesh 38]

I've been rolling this idea in my head for the past little while. What if Celestia is running out of magic? She's powerful enough to raise the sun, and yet she was knocked down by Queen Chrysalis with one hit. I know it's explained that she got so much love from Shining Armor that she's now super powerful, but what if Celestia is just weak after a thousand years of managing day and night as well as running a country, and I'm sure there have been more than a few villains she had to fight alone before Twilight unlocked the Elements of Harmony.

 

She won't tell any pony about it because that might cause worry and panic because every pony depends on her. From what I've gathered from Celestia, she's the kind of pony who would put on a brave face and a fake smile because she doesn't want anyone to worry about her. 

 

She needs Discord because she needs to delegate more and more responsibilities to others because she no longer has the power to properly run things. Maybe she's even getting ready to retire the way most royalty does.

One guess is that Celestia had a theory about Fluttershy's abilities and put it to the test. She may have researched a bit on that before giving Fluttershy the trial (Celestia may have witnessed Fluttershy counter-troll Discord on Season 1). Celestia may have tried reforming Discord in the past and failed and finally found the pony that could have a shot at it.

What's her rationale?  This just hit me, and it's very simple. 

 

She's Trollestia, people. 

 

Think of her teacup trolling on an epic scale.

Permanently sealing away Discord could in fact be a problem, as another member has previously stated.  Perhaps this is another test for the mane six on their way to greatness.  I mean, it's kind of uh, extreme, but it could be a test nonetheless.
