Cygnuses are unavailable.

I'll tell you why I'm not excited: I CAN'T TAKE THE IDEA OF GETTING TO LEVEL 200 BAWWWWWWW! Also, they really should have done it all at once because story-wise it completely doesn't make sense to revamp them one by one unless they had to retrain to make use of the new granted powers.

haha, true enough I guess.
Thunderbreaker i'm guessing is going to be the only Cygnus Knight available for about a month, until Wind Archer is updated.
(Wind Archer is confirmed to be revamped in February. Pirates and Bowmen getting love first, this is weird.)

Which could make sense I guess? Orthodox martial arts are probably easier to train than ninjutsu and magic would, and there aren't exactly many ways to use a bow.

Swords though...I've got nothing on why this would take all that long. A switch to a completely different school of swordplay?

I'm guessing that it would be less about Swords and more about Soul. They'd need to strengthen their soul by... meditating, or going on a journey or something.
