Throwing my two cents here, there are several things you can do to help make things go even smoother, assuming you're leveling out of PotD. If you're in an FC, there are actions you can use that increase the exp obtained in battle. Barring that, there're items you can get from squadrons or buy from your GC to give similar buffs. Then there's food, which is a flat 3% increase to battle-exp.
If you happened to pre-order SB, there's also the Ala Mhigan earrings which buff experience up to level 50.

These things make a difference, especially when they stack.
