I don't know if I want to call it a game with "nice people". If I can jest a bit; FFXIV feels like a hugbox for mentally unstable players who do erotic roleplay in Limsa Lominsa or Uldah. And by coddling this demographic, you make a different "toxic" environment. It looks like it's nice, and players appear to be nice. Then you queue for harder content, and you realize that everyone wants to be treated like a diva and they can do no wrong.
You'll go into Stormwind or Orgrimmar general/trade chat, and you'll read some dumb shit, but I think WoW strikes more of a balance, and it actually bothers to teach players with multiple levels of difficulty. The community is a lot more professional too.
