[Radacci]

He also says something about the new xpac being underwater, underground or on the moon. Fingers crossed for underwater!

ya and considering that one CS, where we see warrior of darkness....

OMG I'm so hyped...I have no idea what Blue Mage even is but I'm hyped

[Vydos]

I'm honestly hoping for underwater with us being able to swim. The water in this game is too pretty and I often feel like wanting to swim in it.

In the rest of the series, blue magic has been about copying enemy abilities and using them yourself.

I have no damn idea how it'd work in an MMO, but it's neat to think about.

In other FF, Blue Mage is a mage that uses monsters abilities against opponents.

It worked in FFXI. You would be able to learn certain spells at certain levels. Your artifact job armor would help you learn spells. The enemy would have to cast the spell to learn it. If your magic skill was high, you could learn it. There was some RNG to the system in that game.

My fondest memories playing blue was having to ally with 12 other players to learn some skills from incredibly tough monsters.

"There are also two NPC talking:
What comes after white and black? I say red.
Red? Don't you mean blue?"

So Red Mage, Blue Mage and Samurai maybe ?

The resulting squee would be heard on the International Space Station.

Soooo yeah cannot wait now <3

That is actually quite cool!
They can bring any job from ffxi and I would like that, the variety they had in xi was really enjoyable and made playing each one interesting.
The more the merrier! I hope to see every one of them in game one day if possible
