Playing devil's advocate here (again, 16 years in WoW, 4 months in XIV so I have some right to talk here) the WoW community is hot garbage. It's not just a generalization, it's like a super majority (though not everyone of course) It was nothing to be told daily in WoW, sometimes multiple times a day in that game to uninstall and/or kill yourself. Public trade chat filled with racist, homophobic xenophobic garbage 24 hours a day. Not just sometimes, but like all day, every day on servers like Area 52, Ilidan, and Stormrage.
The worst I've seen in this game is a "omg whats wrong with you" and things along those lines.
The fear of not wanting this game and/or it's community to be infected with WoW is in my opinion very valid, and as a WoW refugee myself, a fear that I share.
