That is right. Main goal is to create a fully lightning build and fix the damage and rotation issue the Tempest has. A better detailed post was here, with which I mostly agree:
Right now the Elemental Stormbringer in pvp is very underperforming. We are basically stuck with the Lavaburst (farseer) build. It was fun during the Dragonflight when it emerged over time, but then we had the 3rd tier set bonus that gave us 3 cleave stacks instead of current 1 stack. This in my opinion greatly reduced the fun of that build even though it is indeed very strong.
I think tempest should be an alternative to lavaburst. I would also go as far as to recomment being able to replace fireshock with lightning rod instead. To me it appears everything lightning related in Elemental is automatic passive effects, we have no agency over it, and very underperforming in damage.
What is your opinion on Stormbringer guys? Maybe things are different in PVE.
Tempest should work like this: Every 300 Maelstrom spent , the next time you cast Lighting Bolt or Chain Lightning, you additionally cast Tempest at your target.
Tempest can’t replace LvB because it would do the same for Enha and that would mean it would also replace their Elemental Blast. It wouldn’t make sense. You have to look at things from many angles to make it work.
anything other then replacing lightning bolt would be an improvement, but i really like the additional cast idea burst would be insane tho so its damage might have to be reduced then
