As it has been said, you'll appreciate it unless you enjoy being stopped and told to come back when your level 54/55/57/59 multiple times cus the story seems to stop after like 2 or 3 check points.

Considering level sync exists, and there is no PvP level ranks that can't be accessed once you pass them like WoW, it's a bit of a pointless feature.

At worst, you'll have to do a few less moogle sidequests in heavensward, and trust me, that's a blessing, not a curse.
