First of all, Stormbringer looks great. More Lightning is what I’ve been wanting to see for Elemental and Stormbringer certainly delivers. That being said, I have 2 major concerns.
My first concern is the lack of control over Tempest.
I really dislike the idea of not having Tempest on demand. Having to burn through 400 Maelstrom before getting to Tempest is going to create a lot of situations where the enemies are already dead by the time we get to actually cast Tempest.
For this reason I think Tempest would be much better as a separate spell able to store multiple charges or activated by Primordial Wave.
My second issue is the lack of support for Storm Elemental.
I would very much like to make a Lightning build that capitalizes on Storm Elemental, but all the talents that support using an Elemental have far better synergy with Fire Elemental. And if I want to maximize uptime on Storm Elemental I have to spend a LOT of gcds not casting Lightning spells, which defeats the purpose of having the Storm Elemental out in the first place.
I think an adjustment to Stormbreaker’s Fiery Demise could resolve this issue by creating synergy between the Lightning spells and Storm Elemental. The goal would be to allow players to obtain a similar uptime with Storm Elemental as with Fire Elemental without having to sacrifice casts of Lightning spells for the sake of increased uptime on the Elemental.
To that end, I suggest the following:
Stormbreaker’s Elemental Demise - If Fire Elemental is known, Flame Shock has a 50% increased critical strike chance and its damage over time critical strikes reduce the cooldown of Fire Elemental by 1 second.
If Storm Elemental is known, your Lightning spells have a 10% chance to cause your next Lightning spell to gain the benefits of Stormkeeper and your Elemental Overloads reduce the cooldown of Storm Elemental by 1 second.
Overloads reducing the cooldown of Storm Elemental would allow the player to use Surge of Power on Lightning Bolt for the additional overloads. This would allow the player to actually utilize the Storm Elemental for more Lightning spells instead of spending half your time casting Fire spells just to extend the duration of the Storm Elemental.
Additionally, with Primordial Wave serving as the catalyst for Farseer and hopefully being considered as the catalyst for Stormbringer’s Tempest, I would like to see Primordial Wave adjusted to have more synergy with Lightning builds. I suggest the following:
Primordial Wave - Blast your target with a Primordial Wave, dealing Elemental damage, applying Flame Shock, and causing the target to become a Lightning Rod for 3 seconds.
You gain Primal Power, causing your next Lava Burst to hit all targets affected by your Flame Shock for 80% damage or your next Lightning spell to Overload an additional time.
This would allow the player to choose between hurling a bunch of Lava Bursts as it currently does or dishing out a Lightning spell with additional overload to funnel into a Lightning Rod. Casting one or the other consumes the effect, preventing the player from being able to benefit from both.
