Personally, I'd rather see names of real-life nationalities than one more character with a name that looks like it was created by the author's face crashing into the keyboard during a violent sneeze. >,<

In short, the cold hard truth is that if every name in your whole work sounds like you pulled it blind from a Scrabble bag, it's going to feel like you did.Like there really are no nationalities or races or languages, but one: nonsense. If all the fantasy language in your work sounds like nonsense, and nonsense of the same sort, your work looses half it's charm, and half it's 'believability' in one flaw. The language becomes a barrier to enjoying the story, instead of a help to enjoy it.
