As a new player, I really don't want jump potions.

Won't. Not can't. They can always hire more staff. Something they should have done years ago.

But yeah, why do that? Free money! People are more than willing to pay to not play your game.

They have been actively hiring for over a year. Practically every live letter they invite people who are interested to apply.

I think you drastically underestimate how much work it would entail. To do it effectively and keep it high quality and engaging, they would basically have to go through the entire story, figure out what they could cut out, then figure out how they can work around that, then basically rewrite the whole thing, checking for consistency the whole way. Cutscenes would need to be modified and revoiced. Its not like they can just trim bits off and it will be as good as new just shorter. All of that is ignoring the fact that in two years time when the next expansion comes out any gains would have been lost due to the MSQ being even longer.

Without negatively effecting the story for new players and old players there is no easy way to do it.
