Enhancement didnt really receive a buff.Enhancement had some buffs on talents that were already weak in their talent brackets and still the same talents fit in most situations like in 8.0.What we learned from that is that we can be the same bad in more situations than what we used to be.Problem still is the Shamans lack of things that made it feel special in the past.We were never topping the meters like Rogues or Mages did for most of the years but we always had a place in every raid because our class had specialities that were important in like our buffing totems for example.Now we are just battle mages,lacking damage and situational roles in everything and still getting rejected in every activity we are trying to do with pugs and for many of us even in guilds that asking for rerolls.
