Unlike Chrysalis, Sunset never achieved her main goal, not even temporarily. As for the mind-controlled students, the most vaguely credible use for them would be as a meatshield to keep everypony else busy and allow Sunset to focus on Celestia. This is all, of course, assuming Sunset in her demon form even has the capabilities to take on the ruler of Equestria. Whatever her intentions might have been, though, Sunset’s plan was still overall far more haphazard than any of Chrysalis’s past exploits. That much is undeniable.

Not perfect, but her “plan” (she was kinda corrupted by magic so technically speaking she wasn’t at her 100% mentally speaking) wasn’t exactly that bad.

@cloudkicker108  

 
I disagree with that

@Chuy Ryu  
Sunset isn’t perfect by any stretch of the imagination. Among other things, she still has occasional anger issues. As a villain, she was even more incompetent than Chrysalis.

Shhhhh, folks don’t wanna admit that no one is perfect!

I presume we’re only talking about villains here? Because things like “do every event in the Sisterhooves Social in drag without practicing”, “lock Rarity in the window display”, Starlight’s idiocy with the maulwurf (she herself acknowledges how stupid it was), leaving Fluttershy in charge of Rarity’s store, trying to slip Big Mac and Cheerilee a love potion, and of course “If I can’t find a friendship problem, I’ll MAKE a friendship problem!” are also pretty poorly thought-out.

How was she supposed to take over the world with a white Michael Jackson anyway?

I knew I should’ve added genetic codes for QMP* receptors! That would’ve made my chimeric test subjects more submissive!
 

@Ardashir  
That’s probably one of the few things she had going for her.

@SinnerWhoKeepsTrying1978  
Ah, but she didn’t have Vampira, Tor Johnson, and Fake!Bela Lugosi to enact her evil scheme, now did she?

Yeah 3 times in a row.

Or she simply doesn´t understand how the elements work.

@Chuy Ryu  
What episode were you watching?

She never had a single good plan in her life.

@Chuy Ryu
 
So did a lot of characters, I’m just trying to give a plausible explanation.

She had a better plan than those aliens from the Plan 9 from Outer Space movie.
 
…
 
Which really isn’t saying anything.

@Chuy Ryu  
“Make Starlight look better”? Did she even interact with Starlight in ANY capacity in this episode? It looked to me like the mane 6(7?) didn’t even know she was there and she was completely outdone by the minions (mostly the Twilight clone) she created that same day. There’s no ‘but Starlight’ excuse to make here, Chrysalis just sucked.

@Twi_Clown  
nah, she was just touched for the “make starlight look better than others” nerf

@Background Pony #83FB
 
Maybe Chrysalis got her best ideas from the high ranked minions, when she’s for herself she can’t come up with good ideas herself: she didn’t had generals and advisers to help her.

that what happnes when your life revolve around starlight

It mainly boiled down to the clones being 1: traitors at the worst and imbeciles at the best 2: it’s apparently a new spell she created.
 
Problem now is that she knows where the Tree is and that it has a failsafe. Next strike she does is likely going to go much smoother.

…twice!

This; unseen she can kidnap every princess, the elements, and the leadership of the crystal empire. Onscreen, she ignores hostages, picks a fight with celestia for no real reason and generally gloats. Onscreen from the start, this episode.

True, but it’s a VERY interesting plan.
