Remember finally beating that really hard quest? Or finishing that expansion? Well, imagine doing that over and over and over and over and over again for each and every character?

If there's a quest chain that takes me 2 weeks to finally get through, I wouldn't be too keen on doing that all over again when I wanna play another job.

That's not to say I won't help people do the quest when I'm done, but starting over again for each character? yeah...no.
