I got into this game for the story (having previously played SW:TOR, another MMO with a story focus) so buying a skip potion would be completely antithetical to me. But I had a friend who got bored around the end of HW and skipped to the start of ShB. That was her choice and I don't fault her for that. So if you're looking for acceptance, I'll just say: you do what you think is best for you, and don't let anyone tell you it was the wrong choice.
