I imagine if they added chat channels you'd see that area improve a bit, and also might justify harsher punishments for using it as a chatting space for mentors. I believe at least part of it is people wanting to have discourse with strangers in a chat room but SE not really offering that while playing the game, else you have to park yourself in a city (which if you go to Limsa or Ul'dah you'll find).

Of course then you'd get to see the joy, peace, and total zen of general chat channels and I assume some would want these masterpieces optional . I tend to get a kick out of listening to Xroads general chat back in the day, but it was certainly not always above board lol.
