Yeah, I liked aethercurrents! They were fun to hunt down, and gave a good feeling of accomplishment once you had them all and could take off on your flying mount of choice. I agree with Colorful that ditching the quest-based ones would be better, though; just keep the ones that make you explore the map.

There are 3 days of events, TWO concerts, and we're only a few hours in. I doubt many who are there are seething with rage and regretting paying for their ticket.
