No no no.
Looks like I'm in the surprising minority here. If I'm DMing, I simply don't allow idiotic names like "Shooter McBlastypants the Evoker" or "Ikill Youall the Barbarian". I also notice I tend to favor more "roleplayey" games instead of hack-and-slash. These names simply ruin the modd for me.
Now I don't mind odd, or subtley amusing names... Especially if there's a good backstory behind it.
"Kordt Coldbane" is one that is on the edge of too silly, but is subtle enough that you have to say it a few times to "get it".
Later!
