KMST 1.2.482 Zero

Pretty sure nexon intend it this way. They did specifically sell them as "one is build for mobbing and one is build for bossing" I guess the tagging is just a necessary tool to give players access to a job that literally has EVERYTHING. I mean looking at all the stolen mobility skills lol. Zero is the mixture of all the "GOODS" of every job we ever known plus equipment spoon feeding(not complaining here)

They definitely didn't sell Zero as 2 chars which you play separately. And if they indeed intent for players to use them separately Zero would be a failure of a job. It would merely be Luminous 2.0, with a character sprite that switched from male to female instead of a hovering orb and with twice the skills, a lot cloned within its own jobs.
