Elemental Shaman Tempest Rework Proposal

HI,
In this thread I have included the various changes I would make to Elemental to optimize it → Elemental Shaman Rework

STORMBRINGER TREE REWORKED
https:// ibb. co/31SZBjb

I have reworked a lot of things about the Stormbringer tree.

UNLIMITED POWER (Reworked Talent)
If Surge of Power is active, and you cast Tempest, increases you critical strike damage by an additionnal 20% for 12 sec.

STORM CALLER (Reworked Talent)
Increases the critical strike change of your Nature Damage spells by 10% and the critical strike damage of your Nature spells by 10%.

Unlimited Power essentially provides the same effect as Primordial Fury and solves the problem of having to consume Surge of Power with Tempest as Tempest replaces Lightning.
Storm Caller only received a 5% buff on critical strike damage.

FURY OF THE STORM (New Reworked Talent)
Your Nature damage critical strikes increase your movement speed by 10% for 6 sec.

Slowing enemies can be a problem in certain situations, Fury of the Storm provides an alternative.

STORM SWELL (Reworked Talent)
When Tempest strikes one or two targets, gain 30 Maelstrom.

ARC DISCARGE (Reworked Talent)
When Tempest strikes more than two targets, have a 25% change to have another Tempest.

Storm Swell and Arc Discarge, were a tricky choice for Elemental. Now I think they’re more in tune.

ROLLING THUNDER (Reworked Talent)
Summon a powerful Lightning Elemental to fight by your side for 10 sec every 50 sec.

Tracking Stormkeeper procs is a problem, with this change to Rolling Thunder we no longer have to worry about it. And it’s a themed effect.

NATURE’S PROTECTION (Reworked Talent)
Targets struck by your Nature damage critical strikes deal 5% less damage to you for 6 sec.

Nature’s Protection and Surging Currents have been changed to be available more often.

SURGING CURRENTS (Reworked Talent)
After you score a critical hit, your next Chain Heal or Healing Surge will be instant cast and consume no mana.

VOLTAIC SURGE (Reworked Talent)
The damage dealt by your Earth Shock, Elemental Blast and Earthquake’s Elemental Overload now is at 100% effectiveess.

AWAKENING STORMS (Reworked Talent)
Lightning Bolt and Chain Lightnning have a 20% change to generate a stack of Fulmination, up to 10 stacks. Every stack grants you 0,5% haste. Your next Tempest consume all stack and gain 1% increases dammage for every stack.

Many Elemental Shaman have asked, several times, they want to see big damage from our spenders. The change to Voltaic Surge could be the right step in this direction. Awakening Storms makes our Tempest feel much more powerful and grants us some haste.
With these changes (especially Voltaic Surge + Awakening Storm) they should patch up our low ST dps.

These are my proposals.
