Naoki Yoshida has stated that the development team is deciding between two options.
- Jobs become "specializations" within existing classes (i.e. a Gladiator can specialize to become either a Paladin or a Dark Knight).
- Jobs become "advanced jobs" in addition to existing classes (i.e. a Gladiator or Marauder can become a Dark Knight).
What we've been discussing thus far in several threads is which should be implemented, how either could be implemented, or whether any should be implemented at all.
