The mass exping is easy. Everybody gets in Grounds of Valor alliances, spams easy prey mobs for like 3 exp a kill, but gets 1-3k exp per page completed Literally any job works.
The only camp I hate is Crawlers Nest, people level 40 in level 1 gear to get exp while afk. As soon as you hit levels for the Obliette, go there. People have to roam kill so no afkers.
Smn can exp in abyssea fine, but it's essentially useless for anything else in abyssea. It is, however, the best Walk of Echos job in the game (as far as I know). The current overpowered pet soloing job is bst.
By the way, they nerfed pets yesterday, no long immune to doom.
