the trouble is not the first jobs, but the other one, the fate don't get the armory bonus, i did check it early one more time.
same the exp in dungeon is not that great for level from 51-53 i had to do about 9 time the dungeon 51. it's a loot and fate can't compare in terms of exp.

they have wanted to increase the time to level up, it's nice, but the trouble is we don't level only one jobs, FF14 is a game where we can level all jobs, if they try to make us choose only 1-2 jobs now it's quite bad.
