To find the coolest names are right at your fingertips:
Google It !!
Choose male/female which ever gender u are playing
then in Google type in:
Romanian female names
or
Albanian male names
or
Norweigan female names
or
Russian male names and on and on
a dictionary will come up with names from the country you chose; u can choose by name meanings (death, knight, strength, rune, spells etc. I am sure u get the idea), or just cool sounding names according to the type of character you are playing. (my DK name was found in the swedish dictionary)
Take my advice-u will have an original and personalized name to fit your character.
In my opinion (and I know everyone will disagree with me wholeheartedly) the WOTLK has a decidely "viking" feel to it: Norway, Sweden, Denmark, Finland, Lapland, Greenland, etc. A bone chilling aura surrounds the DK, thus a name from a bone chilling location.
Hope this helps! Just don't randomize!
