What classes could share gear with ninja?

[Raikai]

Only thing that distinguish them from each other is the use of DEX stats being Scouting is for DEX Melee Jobs and Aiming is for DEX Range Jobs

Creating a 2nd Scouting Job will mean that the Job will have to be a melee DPS Job.

I still don't understand in practice what is the output difference, it's all physical damage in the end that comes from the same stat. It would be certainly less of a concern "Oh we must create another scouting job just to have something together with NIN". Also if they would really go for balance with the next DPS job added, it would have to go to either Aiming or Casting, as melee physical got already 5 jobs... Which would leave, once more, NIN as the sole owner of Scouting.
