My Jett Revamp Idea

Great idea for the revamp. I LOVE it!

I have some suggestions...

JETT should have a different effect in Character Card... instead of adding time to summons, why they won't add an increase of Mastery?
Like:
B - 2%
A - 3%
S - 4%
SS - 5%

Also changing the class of the JETT as a "Cerberus" race instead to being considered as an Adventurer would be ideal to see. The race from JETT would have loads of potential....

Well, I wasn't really putting Character Cards as a high priority, but sure. Summon duration sucks IMO anyway. As for Cerberus, they'd probably have to give Jett a new character ID due to it not being classified as an adventurer. But that's another story.
To be honest, I wish for a different planet name than Cerberus. I don't like thinking of three-headed demon dogs whenever I think of Jett. I'd change it but I don't want to retcon it too much.
