I've been exploring around all of Ul'Dah and Limsa Lominsa. I really like the northern areas of Limsa Lominsa. You see a lot of the same type mobs but they progressively get more difficult and their names/appearance change a bit, but then you start to see level 40/50 mobs like Blasts/Storm Blasts (land-bound dragons), some small winged dragons, giant salamandars, large goobues that look like they can rip your head off with one swing, some giant bull-frog type mobs as well.
I had fun trying to just run around and grab all of the aethryte (telepoints) without grabbing aggro. Some of those areas are tricky. With not all in-game content available yet, I just wanted to have some fun exploring and it was well worth it. I also found some very nice fishing spots that I will keep to myself for now ;)
Oh and beware caves... they have "Fallen Soldiers" which are outcast/bandit type NPC's that will rob & kill you.
