What I wish I could find is a level by level character guide for each class. Something like, as a MNK lvl 20-25 we recommend "this" equipment if your doing "this" with your MNK, or "other equipment" if you prefer to use your MNK "alternate way". You can go on "these missions/quests" to get "this useful" MNK equipment at these lvls. Quests that can also be completed with this lvl MNK are "these".

It would make it so much easier if someone had a class guide that goes through the levels than it is piecing the information together from all the other sections.
