Along with agreeing that Abyssea access should be restricted to at least 65+, I believe there should be some incentive to leveling those lower jobs in ToAU or Old World areas. Even if you don't add a level restriction, this would increase the use of older areas: Why not add some really awesome job specific conquest/imperial points items at a very high point cost? I know that would be annoying for many, particularly those who would rather level fast and dirty as getting those points would be difficult, but those of us who enjoy a bit of that old school flavor would trade in our time for stuff. Seems reasonable to me.
