Why did SE decide to make the three new classes not require base classes?

Well best we can tell now these new Jobs may have the same requirement as Rogue unlock, being require lvl 10 to unlock Armory for new characters.

Not to mention their location is unknown and being Jobs these new Jobs may not have Guilds in a City State like the classes so the Job Trainer location is most likely out in the world or in a specific location.

Good point!

It could also allow the way players enter the game brand new remain as is, going through the same tutorial. It would be way easier on SE that way.

Although, since we are on the subject, it makes me wonder how we will gain our new skills when the cap is raised. I've only gotten a few jobs unlocked, but in all of their cases, their storyline is tied up rather neatly. Will we perhaps have a new NPC to learn from?
