Hints at new class? Maybe?

It's probably too early for hints. A new expansion will probably come out next summer, but we likely won't get any info about it until at least E3 in June, Tokyo Game Show in September, or potentially Fan Fest 2018 in November.

If we are going to Thavnair, there's a very very high chance we will at least get Blue Mage, given its near-eastern aesthetic and the fact that Blue Mage and Blue Magic has already been name dropped several times already. I have a feeling that Alphinaud will be the Scion's Blue Mage as Alisae was the Scions' Red Mage. He wears blue a lot, and has a blue hair tie. This is the very first time we ever meet the twins. Notice both of their color schemes. It was already foreshadowed that Alisae would be the Red Mage.
