FFXIV is played by millions of people.

To expect all of them to act uniformly, like all the players are robots manufactured by the same factory with the same programming, is idiotic. Of course you will meet arseholes and shitheads in the community.

Though by FAR this community is filled with more positive people, or at least people that do not directly act like arses whenever they're inconvenienced, in my personal experience.

Though it should be noted that I play in Japanese server, so maybe the culture is just different in NA or EU servers.
