well its no surprise that /all /shout is most of time the worst type of chat you can find in any MMO, i have played plenty, and in my experience, they are really cringe worthy for the best.
but there where two of those i played where you could either mute or delete the category of /all /shout chat. and it was beautiful. Due to the nature of alt tabbing in order to chat in other programs or just check the database/wikia for items or things like that making chat tabs change, sometimes you snap the eye on some comment thats incredible uncomfortable. And thats not very cool.
so, what i am sugesting is simple, i know that nothing is simple in programing and it requires time, effort, money, headaches etc etc etc, but if a feature like blocking/deleting/muting the /all tab in this game. It would be nice.
note that its not really necessary, its just because, /all right now is very toxic. All thanks to xenophobic drama thats been going on. And you know… when you just want to play but your eye catches a glimpse of what is going on, sometimes the stuff people say ruin the mood.
