I actually don't mind the aether current system at all. I think it was a great way to get you to explore the area and see what the devs built before allowing you to skip over it all. The only thing i would have changed is the location of a few of the currents (Dravanian Hinterlands, Y U make me run around the whole zone for 1 current because of 5 yalms z-axis? >_<)
