Have you ever ACTUALLY played DnD and seen what players will come up with for vicious mockery insults?
So? The appeal of cRPG is to have competent writers and designers behind the campaign. Coming up with insults must be a tough job - though only two acceptable solutions are:
1) pull it off
2) find a way to convey the idea without having to write actual insults
[as a sidenote, I don’t have as of now an opinion on the subject, as I didn’t play the patch yet]
