In 7.0 what do you guys think Alisaie's...

[Zanarkand-Ronso]

Shes not gonna get one. She already went from Arcanist to Redmage.
Alphi was the only Scion who hasn't gone through an Evolution, and now he has as a Sage.
In depth analysis of the Trailer/Incomplete version of the Opening suggests that Zenos might represent the 2nd New Job. Plus there is what he says about needing a new weapon.

[Theodric]

I don't think it would make much sense for her to get another new job. I don't particularly like her as a character in the first place, admittedly - but she's the RDM representative among the major characters. That suits her well enough. (Though I'd much prefer to have X'rhun Tia at our side!)

Alphinaud is becoming a Sage, but I'd prefer not to have every new job represented by existing characters. I want to see some new characters introduced. One thing I disliked about 5.0 happened to be the lack of new travelling companions.

...new job class will be?

Please share your thoughts here!

Personally, I feel like she'll end up becoming a physical dps that focuses on a fighting style similar to RDM where she works to build up aether in her weapon, but much faster and without a cast timer strike at her foes much faster than she ever could as RDM.

I think she stays as RDM.

I think Zenos will get the new melee class.

High hopes we don't have her around for 7.0. Nor her twin brother

Now that you mentioned that... I started speculating, since so far 6.0 got a few elements that clap back to FFIV. And there we have twin siblings making a sacrifice. I wonder if such a thing can happen here.

[Vahlnir]

If I were a betting man, I would bet that RDM will be her job for the foreseeable future. I don't really like her character at all but RDM suits her.

[Themarvin]

would like to see her to grow to be a fine woman... likewise would be awesome to see ageing decay and changes on the Characters in this game...

[Bright-Flower]

I don't expect any more job changes from the scions. They don't change jobs all the time and I feel like they're all setting into good spots for now. The reason SHB had so many was to work them into the roles for the trust system.

[Edax]

I'm guessing she stays as a Red Mage because in lore she's like the 4th red mage left in the world.

I thought recently Yoship said she won’t be getting a new class, just a new outfit (and we’ll be surprised who she gets it from). Maybe I misunderstood the translation. I don’t think she’ll be getting a new one.

I think RDM fits her character perfectly. Action oriented but with healing abilities. It made sense for Alphi to learn a new job though, since he’s been an arcanist from the getgo.

That's exactly what he said, yeah.
