Honestly, the more I think about it, the more basic it seems. Spiderman is outfitted in red and blue. It could be as simple as that.

The other thing, is didn't they originally say back before Heavensward that they were trying to decide between Dark Knight and Samurai, and they chose Dark Knight. If we are really only getting 2 new jobs, what would be more likely a tank and a DPS, or two DPS?
