It looks like they need to increase the overland mob population by about 5x
Walk around a little, its not gonna kill you to explore, there's plenty of mobs - i'm not saying they should increase the number of mobs but some of you are only good at complaining, god forbid you run around a little to find some mobs. Right next to camp Black Brush in Ul'Dah there's a hill overlooking the camp, there's about 30 Marmots that spawn there at the same time (literally, 30, and all clumped together)...just look around. If you started in Limsa, try the caves, try the mole camp, group up with one other person and take on puks if you're capable...Dunno about Gridania someone else can help you there. Mobs aren't that sparse.
