@Braveking i get the appeal, but Blizzard saying 'Delve-like' makes me wary. If the rewards are really good, people will optimize the fun out of it in a week and it turns into another chore list.
Right, but in practice players still see their damage go down and call it a nerf. Blizzard can say 'bug fix' all day, the raid leader just sees the meter and starts making faces.
