There's a logical similarity between ninja and dancer though - far more than I see between dancer and (essentially) archer or gunman, which is a very different type of projectile weapon, even if both are "ranged".

Ninja and dancer both rely on physical dexterity and precise movements, and both use some similar ranged weaponry: throwing-knives and shuriken were among the potential weapons mentioned for dancer. Chakrams also inflict slashing damage.

Combined with the potential for balancing the number of classes using each type of gear, Scouting seems like it should have been a good option.
