I want to believe in the Sam Raimi theory, simply because I at least can imagine forcing myself to play Samurai.
My dislike for both Redmage and Bluemage is so big that I can't deal with the thought of 2/2 jobs being something I won't ever play x.X

If, in some convoluted way, it was actually meant as a hint to an acrobatic class like Dancer, Juggler and the like, I'd be incredibly happy, but..idk...seems unlikely.
