I'll live with it if they don't implement this, but it will ruin my experience a bit... Make it less fun for me.
That said, when I play the good path (did evil this time just to get to new content faster and to see what it was like; disappointed Minthara's not a companion yet) it probably won't be an issue. I'll likely kill all the duergar anyway. Then I won't hear their smut talk.
Now isn't that ironic? To not hear vulgarity I have to murder a bunch of people? Is this really the good path?
Lol
