don't forget your resting bonus when you log out. Make sure you're either in an inn or on your FC home property. Don't just log out in a random place. Synestr gave all the right answers. Roulettes tend to give the biggest bonuses, so do them first. I have two level 50 classes and one 49. I save my Leve's for mining and botany, but I definitely run fates. I recommend not running those you have to level set for, except "It's Not Lupus" in Costa del Sol. That's a tough one with good rewards. Obviously, the three dragon filled fates in Coerthas that end with Svara (sp?) are the most profitable. You get between 40 and 50k XP depending on your resting bonus. The fate "Eyes" is a good one, but that's tough. You see tons of wipes and resets with it, because he uses 100 ton swing or something like that. It kills every human and chocobo in its path. Without a party that has a tank that knows what he's doing, that one is a nightmare. The adds, the swings, and some hot-dog tank or bard that kites the cyclops around usually makes this one a pass for me. I can get more from Belly and Saints because they pop more often and I can solo them. Join a party and drink/eat xp bonus stuff. Don't worry about your iLVL for fates, you can wear that stupid looking level 1 hat that increases your xp so long as the rest of your gear protects you. In a party, you share XP, so if the tank has aggro, you can increase your xp like that. Good luck.
