Meh, this is lacking....

1) 1-15 fates in limsa
2) 15-30 low level roulette/levequests/occasional spawned fates quarry mill (or dungeon runs if you're a tank/healer. Dps queue's really ain't worht it, when you can do 8 leves in 10mins, giving you more exp than a dungeon)
3) 30-44 Low level roulette/fates in Camp Dragonhead. You should also do all lvl30+ guildhests, cause the bonus exp returns with every new class you do it with for the first time.
4) 44-50 Low level roulette/Dzeamal Darkhold first room spam or just do it over and over. Do some fates in Camp dragon head while you wait for the queue to finish. An other way would be doing fates at the power plant.

50-60 will most likely be another fate grind for most people till it dies out again.
