“Dancing” between elements it’s the only reliable way to do decent damange and keep good survivability (→water, heal, and switch; →earth for protection)
i may quote you devs saying elementalist is uneffective at damage mitigation in PvE.
I also can suggest you that going full offensive is the best choice on fractals.
But if you think you could have some problems just go for a knight set or something similar.
Just keep your zerker weapons (and maybe a focus with some vitality on it)
I absolutely do not recommend conjured build for fractal.
As a lvl 49 fotm with 350+ pristine this is my opinion.
A PvE player is supposed to avoid a 1-2 second 1 shotting aoe.
A WWW player is considered uncapable of avoiding a 5,75 second aoe for half his health.
Look at my sig. I have a guide just for that topic.
