I'm only sharing with you what I see around me because I don't believe that people are so drastically different.
There are strange folks who like to jeopardize runs in JP DCs, too, but it just doesn't happen all that often, and I can't believe all pug players in the NA/EU are like that.
But, as you said, I don't play in NA/EU and that is a magic word that I can't repel
I just hope the NA/EU discord community would be a little more forgiving of the non-discord community in the future.
It is an optional outside tool and various people have various reasons for not installing it.
