I really wish they would dump the help text boxes and do a more interactive tutorial method and do things like when there would be an active help popup, instead grey out the screen, show you where the thing is they are talking about and have you click through what they use text to explain so you can actively see how to do different things instead of having a series of text boxes to read with no interaction.
I agree that the job quests would be a great place to more actively teach new players how to play the game.
