Leveling as a returning player?

[Afania]

Hey
I recently reactivated my old character (69 PLD, 65 WAR, 49 DNC) and I've found that I really don't know how to level.
Last time I played leveling consisted of GoV in Bostaunieux Oubliette, but that place seems empty now. I've tried searching for 'guides' but the stuff I find is from 2012/early 2013.
Anyone have any hints/ideas of how to level to 99, or if it's even possible anymore?

Hope someone can help me, thanks! (:

Lower lv is probably much faster to do coalition assignment. 1 run takes 1 min and less, you can ding 1 lv after every run.　So you can ding 10 level in less than 10 min.

After lv 30 just leech in Abyssea as usual.

For skill up just use books from RoE.
