Last night, as I was working through my challenge log and getting to level 59 for the main story, I took a break and decided to do a bit of exploring. I was in the Sea of Clouds, and I think that region in particular is so much easier to navigate from the air than on the ground. The floating rocks and obscure paths all mixed in with the different levels are just too much for my directionless self.
Soon, me and the trusty compass were at it trying to figure out where all the aether currents were. The last few aether currents proved to be the most challenging for me. There was a point where I was running around in circles for a good half hour! It made my head spin but I was at the same time, enjoying the challenge. Personally I think Sea of Clouds is one of the harder regions to find those darn currents in!
