Repeating the living story steps is fun and I really like the new achievement system – but I think there is a bit of a missed opportunity here. They should add a (very) minimal reward for redoing living stories segments associated with releases – it could be as low as 20 silver or maybe a couple of champion bags.
Turn them into mini scalable dungeons (akin to the missions from GW1) – the only piece missing is a smallish reward.
