Suggestion: Add a little bit of "Dressed to Call" to lvl 50 job quests
For reference: http://ffxiv.gamerescape.com/wiki/Dressed_to_Call makes you gear up in each slot to proceed, near the start of the game.
Nobody likes seeing black mages in mind accessories, bards in strength, etc etc, it makes things harder on them, makes things harder on the people they party with.
Maybe add a little somethin to the job quests before their big fight, NPC saying "are you ready for this? let me check your gear" and have a requirement for at least some of their prime stat to be on each piece.
Because as politely as it can be said, some people do still need something of a walkthrough about how to play before hitting endgame.
