Elitism is not an issue in this game. It exists, but you'd be hard pressed to find any online game with a better community reputation.

Elitism is not some guy offering pointers on how to better play your job. They don't have to be nice about it, be happy they offered you their advice at all. Elitism is not some guy pointing out that you are holding the party back because your damage output is horrid.

Elitism is people thinking they're better than you because they've cleared a12s or links you to their fflogs profile. Xeno comes to mind. That's real elitism. People telling you to git gud because you suck is not. Especially if they're willing to help you out and tell you how to be better, which this community is 99% of the time really good at doing.
