Depends on your class, where you xp, what your intended use for the character is and so on and so forth. It all comes down to how much you're prepared to spend and if you want a low tier pvp toon, that's still in the thousands. Now, about the weapon specifically, depending on its enchantment (and the rest of your setup), you can probably get away with pveing with a dark weapon. The enhanced shadow weapons is another thing for you to consider, while their pve bonus is slightly lower than bloody weapons, they do provide extra attack attribute and are considerably cheaper.
