With all the recent changes to jobs, playing below lvl 70 with most jobs is very boring and broken. They can just allow rogue to be unlocked at lvl 1 and give it a crappy opening quest that tells you something like come back when you are stronger ie lvl 15.

Lvl Sync needs to be reworked imo. As new expansions come out it only gets harder for content that is under the current lvl cap.
