Honestly they most likely wont want to change the function of the skill which is a support/defensive save with auras. We get that it doesn’t work well in practice, so what kind of support/defense elite would you like to see?
-Keep it in the tempest/stormcaster theme
-Keep in mind its a shout and will have an aoe component
-Keep in mind synergies with other skills/traits
Personally my suggestion is to remove the attunement specific auras. Nothing like feeling punished for not being in earth when you need a reflect or being in fire when you need a frost aura. I would want to draw from all attunements at the same time in a stormcaller fashion.
The life save is so weak that if you are taking serious damage its useless due to it only granting 2.2k effective health.
Example new elite personally for me would be a channeled shout that gives you a sandstorm barrier destroying projectiles and granting protection/stability to allies, have it be a stunbreak for the caster(and/or pulse vuln on enemies) and charge allies grant swiftness or quickness, conjure a monsoon in the area, pulsing healing and regen, and grant pulsing might stacks to allies and burning to enemies all for the duration of the channel. When the channel ends, increase the effectiveness of your next attunement overload by 15% and slap on a break bar for balance if needed.
