I think accessibility features should not come at the cost of core gameplay. MMORPGs are fundamentally a social activity and should be designed around that. Support for people who have difficulty communicating should come in the form of e.g. subchannels that you can passively advertise yourself as available in, or prewritten barks for key information that are translated according to user's localisation.

A magic button that turns the other people you're playing with into objects to support your fun is bad and antisocial. Shooting the shit, chatting in a half formed group, whinging in chat and having the server clown on you; these things are just as much a part of MMOs as killing mobs for XP are.

It's fine not to enjoy socialising, and if you don't I would recommend not picking up a social activity as a hobby. I am fully supportive of things that help people connect, but believe it's deeply misguided to turn games that are the evolution of MUDs into parallel play single player + objectified others like ARPGs/shooters etc.
