Check your challenge log, and try your best to make sure you get all those weekly bonuses on your class that you're leveling. Like the one for commendations, you can do 4 on your SMN, and then if you do the 5th on your ROG, you'll get the full bonus. The best is when you can get the bonus for your 5th Dungeon, your 3rd Dungeon Roulette, and your 5th player commendation, along with your daily low level bonus, all on the same run, you can level twice!

Remember to do your daily low level and daily guildhest on your Rog.

I usually like doing FATE parties for leveling, but levequests are certainly good also. Remember your Hunting Log as well.
