Why does she have to loose something? Her goal was to actually create a better universe, and she got decieved hard by the Jailer. She was never inherently evil even if some haters (or that Afrasiabi dude ...) would like her to be. And in the end, her consequences actually led to a reform of the Shadowlands and a better system for everyone now that Pelagus allows souls to have a word in their judging process. Kyrians and Venthyr also got a major improvement. Her actually having to do something good and help retrieving souls from the Maw is a great ending for now, and I can't wait to get her, Dorithu, Anduin and Nathanos back in a future expansion.
