I personally don't think it's a "I'm running out of ideas kind of deal" if something, it is very clever. You gotta remember the name of the class, Hunter. If you look well it actually lives up to the Class that is part of. Bow, arrows, and knifes are the main definition of a Hunter. So I think that the fact that Nightstalker, a name which also fits the class, it's actually well thought out. At least that's my thought behind it...
