What kinda GM was this?

I take that as a sign they are keeping the other classes instead of scrapping them.

I think it was stated by Yoshi-P that the armory system and the job system work independently from one another. I wouldn't doubt its similar to the Support job system we see in ffxi, and each weapon class(Gld, Thm, etc..) are played as support roles for actual jobs such as warrior, thf, mnk ect. but IDK just a guess.
I am just excited to see where this new content is going ^^
