Tutorials of how to play? OK, I think this should be easy. After your class quests and story through about level 20, the basics should be clear - though the level sync on low level dungeons is not strong enough, so players might not have got a good grasp of things due to being rushed or dragged through dungeons by others chasing bonus tomes. Stronger level sync would help greatly since it would return things to something approaching they way it was when the 1st wave of players played this stuff, it was all new and we had to learn together. Level sync initially appeared to be something that would manage that trick, but it's clear as day now that it's not strict enough, especially later on in the level 50 content.

Once the main story get's kicking, and you get to your 1st job quest, you start on the dungeons that ratchet up the learning curve (or at least they used to when we all ran in level appropriate gear...). So, onto that tutorial of how to play your role, job, class etc...

Try the following strictly level sync'd leveling dungeons, specifically Haukke Manor, Brayflox Longstop, Cutters Cry, Sunken Temple of Qarn, Stone Vigil, Dzemael Darkhold and best of all Arum Vale. Throw in strictly Sync'd hard mode Ifrite, Garuda and Titan, plus WP, AK & PS, and you have a complete set that takes you through your job's paces from level 30 through 50. They cover so many aspects of play, role and mechanic.

Unfortunately since 'everyone' over gears everything, new players are carried through all of this content like so much baggage by high level players looking for extra tomes from Duty Roulette. Mechanics are ignored, bosses are burned and primary roles are blended or ignored.

Baically the game through level 50 is a long tutorial, and has been described as such by Yoshi himself. Sadly though the ineffectiveness of level and ilvl sync greatly reduces the tutorial value of this content.
