They also still haven't fixed the issue where many people (myself included) are only able to do three Vanu Vanu quests a day instead of six. Two hotfixes and it's been left to continue. Honestly, that's something you'd think would be picked up in testing, but guess not.

Since they've already posted they can't find anything wrong with the Duty Roulette algorithm, I doubt that will change. There isn't a great deal we can do except ... wait and hope?
