Agñes should be a unicorn, but well, that gives me the idea of giving all three female roles to Fluttershy. Triple Fluttershy mania. X3

My 2 cents would be:  
Agnes: Flutters  
Tiz: AJ  
Ringabel: Rares  
Edea: Dash  
Yew: Twily  
Magnolia: Ponk

For those who want to level grind, the dragons are always open for a rematch once every chapter after you beat Alternis.

I noticed that monthd ago, i got confused because i no longer had tge dragon orbs and failed to noticed it was becaused they where use in the door and that this carry to the next worlds.

@Background Pony #650A  
Funnily enough, I gave Fluttershy Edea’s leitmotif: Baby Bird.

@RIG  
If you beat the six dragons (Salamander, Mizuchi, Wyvern, Ladon, Shinryu, and Jabberwock) in Chapter 4, you do not have to face them again in later chapters to unlock Lord DeRosso’s castle.

@RIG  
No grinding necessary. The dragons can all be beaten by a single ninja with the Red Mage ability Turn Tables. As can any monster in the game that never braves or counterattacks.

@RIG The funny thing is, the Dragons can be AI-locked via Hasten World + High Jump combo, just need a little more Agility every time and you can truely AI Lock them (just make sure you save, sometimes things can go wrong)

>chapter 5  
WTF? i have to beat the dragons again? hmmm is not bad, i have a strategy that make them a joke…except the fucking dark dragon and its fucking dread status aliment! why no job gives dread immunity?!

@RIG  
You’re only further than me because I have a lot of shit in life going on right now. However, it’s tolerable over time. Plus, the job level sharing thing should be good for either of us. Now, I just gotta get out of Eisenberg. XD

>TFW grinding to get hasten world to defeat the fucking elemental dragons  
exp egg+summoning (fire) spam+next to eternia city FTW.

@RIG  
Im the guy who made it. Ill post my reasoning for each one, but like you said, feel free to disagree.
 
The request was for 4 of the main 6, so i didn’t have that much choice.
 
Ringabel/Rarity - They both have that stylish, sophisticated vibe about them. I thought this was a no-brainer. Who else would have fit, possibly Rainbow Dash?  
Edea/Fluttershy - I realised this wasn’t completely compatible, it was mostly because of Edeas armor. But i guess bitch fluttershy kind of fits?  
Agnés/Twilight - Both main characters, both are magic users(I left ingame Jobs out of it) I considered Fluttershy for Agnés, but i wanted twilight as the main pone in the front.  
Tiz/Applejack - Both quite plain, both farmboy/farmgirl type characters.
 
I tackled this with more of a “Who wouldnt fit” mindset, and Pinkie Pie/RD were the ones that seemed most fitting to leave out.

@Background Pony #EB8D  
and what is wrong with it? the artist made this thinking each pony fits each character, people have the right to debate that, this is not drama BS.

Edea is a tomboy but still much more femenine than RD, it doesn’t fit.

AJ as Tiz? I can see it from a blandness side, could work. Though AJ doesn’t seem the type eager to meddle. . .
 
Twi COULD make a good Agnes, if only based on her season 1 personality. Rash, stubborn and believing herself solely responsible for things. . . it fits.
 
Rarity Ringabell. . . I can see it, but it’s a stretch. Won’t get any more into details with that as Ringy is a walking spoiler.
 
Fluttersy as Edea is just wrong in all sorts of ways. People mention RD as a better substitute, which fits her ‘sees things in black and white’ and often brash unapologetic nature. Flutters just lacks anything that would scream Edea, like, at all. . .

Come on, people. Rainbow Dash as Edea? With that Special Move theme? Get real.

Rainbow Dash as Edea would have fit a lot more

@RIG  
My reasoning was, they both have a main focus on magic(without going into the ingame jobs). Fluttershy in the middle with Twilight in the back would feel strange to me.

@Background Pony #EB8D  
uhh…Twilight as Agnes doesn’t computer either…

@RIG  
@Background Pony #EB8D  
That was me, i just forgot to not post anonymously.

Fluttershy as Edea?  
THAT DOESN’T COMPUTE!

Awesomeness! I just started to play it~ I think a Breezie could be Airy~

They look so cool. Especially Twala

@OPHD
 
Yeah, sorry. I just happened to check DA just as this was uploaded. If you meant to upload this yourself, I apologize.
 
Also, really looking forward to hearing some more of your dreams with Haven.

That was a damn quick Derpibooru upload brah. Hah.
