Elemental is currently benefiting from a beneficial "interaction" when using
Elementale della Tempesta +
Fiammacuore. They are able to keep 20 stacks of
Folata Ventosa 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 and able to drag their storm elemental around the dungeon. Definitely A or S-TIer. The justification written below is assuming that the interaction will get fixed?
Elemental burst AOE and priority damage remains quite good while their utility isn't super subpar. Ultimately where Ele is lacking is on the ST department for dungeons and just the fact that they gain less than other classes with their second legendary acquisition. They do gain a lot from their 4 set
Fiammacuore as they are able to get great value from
Elementale della Tempesta. The storm ele build is one that is quite typical for M+ and anything that interacts positively with Ele is going to be a great bonus. Ultimately they are in the b-tier because of the projection of them not being absolutely top tier damage and getting lightly outclassed by some of the other DPS options.
