I’ve got a little suggestion. As living world events are ‘limited’ somehow, and similar functionality has already been implemented, I would really love to see the timer next to achievement group saying how much time is left to finish them. Its quite difficult to find such information on forums, and also there is no consistency in events lengths, some of them are 2 weeks, some 4, now superbox is third, and name of the “boss week” says that its going to last just a week.
tl;dr; Living world achievements timer showing the end of event, like for dailies/monthlies.
