How is it that Ninja ranks so low in population at 60 to the other classes? Ninja is a super popular archetype (akin to the WoW rogue which ironically became the least popular around cata due to gameplay vision changes).

I mean...NINJAS man. I'm just curious what's so unattractive about the FFXIV Ninja that seems to keep its players from growing like a fungus like most games with a similar class?
