I really enjoyed Surv during the legion pre-patch, but it's not my main; Legion is, hilariously, both the best designed expansion in wow's history, but also the most alt-unfriendly. Even offspecs you're a damned fool if you try to keep them going. So survival falls to the wayside; it suffers the same problem as Priests - Why be Holy when it's on the same class as Disc, or vice versa? Why play melee when there's still a strong ranged spec on the same class?
