Kraylessa on WoW Ladies has a problem I've been thinking about lately as well. When I first started playing WoW, I rolled an NE hunter (yes, I know it's a cliche noob class and race but I was young and impressionable at the time), and while I was able to get her all the way up to 60, I've since abandoned her for another server (because a friend made me move) and for the Horde (because, come on, Horde rocks). I've since rolled up a shaman, a rogue, and a mage, but even after playing and enjoying those, I still long to play a hunter again-- the combination of crazy ranged DPS, traps, and a powerful pet is like a siren song to me.
So I'm faced with the possibility of rerolling the same class I already played, and, like Kraylessa, this is not really something I want to do (at least I wasn't made to reroll because of an accidental character deletion). True, it has been a while since I've played the hunter, so things have changed a lot (not to mention that I've learned a lot as a player). And I'd likely try another spec-- my hunter was a marksman, so I'd probably try a BM (Kray doesn't want to level her priest shadow, but I have no idea why-- shadow priests are hella fun, and if she missed out by leveling with holy the first time around, she owes it to herself to level a face melter).
But it still seems like it would be boring, like a suspense movie I've already seen. Have you ever rerolled the exact same class? Was it definitely worth it or completely a pain? I'd really enjoy having a brand new Blood Elf hunter as a main, but I just don't know if I'd enjoy grinding all the way to 70 again.
