Square could've just muted people who are too toxic, but that requires GM's and money to implement. Much much easier to just mute everybody, even though no PVP game ever has done such a thing, even extremely toxic games like League has never done a global mute haha.

This is just sad. I don't know if it's just the dev team being out of touch with pvp or if they are doing this to save money.

In my opinion it would be better to just do nothing. If people have really been getting that upset over chat in Feast they can literally turn it off themselves.
