We have added a new categorization to the Quest template for the minlevel by race. This means you can go to ONE page that will now list ALL quests in ALL zones that you can now obtain. The subcategories are still being created,and the wiki should fill them in the next 24 hours or so as it does it's daily scan. This is not on the menus, yet, but should be soon.
The first split is for Asmo vs Elyos, then by level. You can see the top level at http://aion.zam.com/wiki/Category:Quests_by_Race_and_MinLevel_%28Aion%29
