is it me or fate/sidequest EXP are bad from 55-60

If you are levelling a Job after the first most of the FATEs in the zones from 52-60 give 40k to 60k and can be quite quick. The Dravainian Hinterlands has FATE trains on my server. Some give more. There are a couple of special FATEs around the place that can net you 100k+.

IF your running FATEs in NT after 52 your going to be going slower than doing it in the new zones.

As for your first class, I would suggest making sure you do your Duty roulettes and your daily hunts to help carry you there. The daily hunts offer between 100k and 175k per bill and don't take that long to do plus you get Hunt Seals.
