Elemental is currently benefiting from a beneficial "interaction" when using Элементаль бури
+ Огненное сердце
. They are able to keep 20 stacks of Порыв ветра
from their elemental permanently by re-pressing storm ele and allowing it to have 100% uptime. If this stays then Ele will probably be one of the best specs in the game. Definitely A or S-TIer. The justification written below is assuming that the interaction will get fixed?
Elemental Single Target seems pretty good with 1 legendary, but once they start to get to 2nd legendary territory they fall off a bit. They are ranged in a tier where multiple slots are open for ranged, so if their ST DPS does stay as good as their 1 legendary counterpart, then you may see Ele being a decent option for some encounters. As a whole they are lacking in the raid utility category, but they can talent into Тотем ветряного порыва
if need be.
Overall, they are pretty good at most AOE style encounters, but there is a pretty big lack of those styles of fights in Sepulcher which is very sad for the elemental shaman. A lot of the AOE style fights have unimportant mobs that can get killed passively with cleave from other specs that lose very little or even in some cases gain priority damage to kill them off.
