People are reading way too much into stuff like the blue and red aura in the Stormblood CGI video.

It's not like any other job in the game has a glowing blue aura...oh wait



And it's not like our main hero represented in these trailers has been the job that had that aura....oh wait



It's not like the primary color for Heavensward was Blue/Azure and that Stormblood is Red/Crimson. People are reaching way hard with this.
