Fastest way to level jobs like Samurai or Gunblade is to do Leveling roulette which can be done once per day. Leveling roulette gives you enough exp for like half a level, maybe more. Moogle tome event returns next week and gives you special rewards like the Gorilla mount for doing roulettes and dungeons.
