I'm looking to play some content I never played before, and one thing I skipped more than anything were storyarcs. What are some of your favorite high level (50) story arcs? Preferably ones with cool encounters, bosses, mechanics, etc. Great story is nice as well, but if story is all it offers then I'm a little more meh on it. Love to hear what you've enjoyed and then try it out!
