I fail to understand a logic behind a guild for jobs. The guilds are class guilds. Jobes are going to be sub-divided specialties of there respective classes. Thats how I took it at least. My first thought is that they plan to have 2 jobs for each class, but that assumption only.

Made up example here. Gladiators have a quest to unlock either dark knight/death knight or paladin/white knight. why would they both need there own seperate guild? there both gladiators. They are simply gladiators o different specialties or different directions.
