Windsong,Lightning Shield, Overcharge, FOA. Yeah.
Sadly this combination isnt supported by our legendaries. Akainu forces enhance into a fire/frost build. The new melee trinket we might end up using is fire damage too. T20 would synergize with 4pt20 though.
We will need to sim it. Either Akainu is bad or Earthen Spike is bad though...
But with Akainu and without 4p, a ptr test ended with 35% lava lash dmg and 8% hailstorm and only 17% storm strike....
