I was reading an article on the Ranger job on Wikipedia(See below)

The Hunter (sometimes called Archer, Ranger, or Gunner) is a physical class specializing in ranged weapons—such as bows and crossbows. Aside from their bow attacks, some Hunters have buff abilities that temporarily raise their stats, such as Aim, which raises accuracy;or Charge, which increases the damage that arrows inflict. They can inflict status effects with specialized arrows, and sometimes can detect, capture, or hide from enemies.
And I think Wakka fits this description. He has the Aim ability and he can buff his blitzball with Dark and Sleep attacks and Elements with his Slots Overdrive. True, he doesn't use Bows or Guns, but he uses his Bliztball for long range attacks. But that's just me though. What do you think? Should Wakka be considered a Ranger?
