Okay so I understand they wanted 60 to take a bit to get to for your first job. But for those of us who like to play multiple jobs it would be really nice to get exp rates boosted in some way. So I'm thinking we should petition some ideas and hopefully get some feedback from SE.
-Proposed Changes-
Armoury Bonus 100% (just like 1-50)
Challenge Log (proper scaling 50-60)
Roulette Bonus (proper scaling 50-60)
Guildhest Roulette Bonus (reward should be something closer to what Trial Roulette is)
Reasoning the amount of experience required to level from 50-55 isn't so bad but getting to 55-60 the required amount really goes heavensward. Spamming a dungeon 5-10 times for a single level is truly ridiculous. Considering leveling 15-50 you could easily gain a full level or majority of it in a single dungeon.
