I don't see what the problem is with skipping. How does someone else skipping impact you? If you enjoy the story then enjoy it. Someone doesn't have to share the same interests as you and enjoy the story. Instead they may enjoy raids/battle content more and hardly care for the story. Honestly when i see some of these replies it just mostly boils down to "because I done it, they need to do it!". The simple fact is people don't want to spend a large majority of their time in old content simple as that. I would rather SE do add a skip potion because then at least people will be inclined to try the Expansion and then perhaps stay afterwards then increase overall sub numbers. Instead of leaving early game and then telling their friends how poor the game is and then their friends tell the same information etc.

All it comes down to is:

If you want to do the story then do it. No one is saying you are not allowed to do that. Yes this game is story-driven but sadly with the current patches you only get some every 3/4 months and the rest of the time your doing battle content or other pieces of content in the game. There is a reason why dungeons have been appearing earlier in the story patches because SE said themselves there are quite a few people who complained and simply don't care for the story and want the dungeon for Expert. So let people skip let them play how they want to play their game and I won't judge them for playing that way because everyone plays in a different way from one another.

Also just a side note. Those that say leveling up lets you learn your class is just a bunch of nonsense and you have no idea what you are talking about. This game hardly teaches you your job and based on "certain means" I can see that just by looking at other people's DPS that even though they are 60 they do terrible damage, can't heal properly or struggle to tank. If you want to learn your job in this game you yourself have to go out of your way to learn it and perhaps look up rotations because the game does not provide it. They only say what the skills are but that's it. Job quests didn't teach me a single thing about my job.
