Well this is an interesting topic. At first I was fully against it, now I am more accepting but still have my concerns.
Many people fear, rightfully so, if I might add, that a bunch of people will start on high level without the first idea about their job. And that will happen. But there is something we must not forget: That happens now too, except for the starting on lvl 60 part. I bet most of us have seen people playing in a way our first thoughts were "They either bought their character or just have no idea in general". That's not a new phenomenon. However, if someone wants to be good, they will try their best even if they bought the boost. I also thought thought "If you can't be bothered with leveling up a job, you should not play it" and while I still partly think like that, I now see many will probably work hard on learning their jobs. Also, this jump potion will bring people to 10 levels below maximum level so they have some training before endgame.
However, I would personally make some modifications. I would not mark all dungeons as completed with it. It just sounds wrong, make them open, sure, but not completed. This is mostly for trials and raids, though.
Also, I don't think letting people jump to lvl 50 (60 with SB) on their first character is a wise thing. I can see people not enjoying, not being interested in story and while I don't agree with them, we all have different tastes and play for different reasons. Maybe let them use a potion that clears all story content, maybe unlocks all dungeons and trials but they still have to level up their first job. This is not a competitive PvP (moba, fps shooters) game where you can jump in, play a very short amount of time and you are already playing with "top" people. Jump boost should only be able to be used if you have a maximum level character. Maybe let the story unlocking potion also increase the XP gained by the highest level combat job of the character, since they won't have story quests to do, until they reach maximum level. I can understand someone not feeling like leveling up several jobs to maximum level but if they can't do it with their very first, they should look to play a different type of game, not an MMO in my opinion.
However, the huge length of story content needing to be done in order to catch up can be scary for people not interested in the story and makes them stop after a trial account ends or sooner.
Maybe also introduce a Hall of the Novice-like feature where people can practice in different scenarios solo or in group.
