Seriously, We've only got a small glimpse of them so far, but from what I've seen, I'm LOVING them.
especially the Everlight site, which looks like its HUGE.
I'm getting more and more hyped for this skill, Can't wait.
What are you looking forward to the most? Personally its the Exploration and Lore for me. It looks like there is going to be a Ton of things to Find and Do/Restore.
