[THEORYCRAFTING] reworked "shadow swordman"; dual wield with Ephemeral Edge

Here it is, sightly reworked.

Since I use ephemeral, it would lack in dps, so critical nodes, using 1/2 mana flasks(can't afford clarity imho, not enough mana nodes and mana regene nodes, but I do have mana leech!), 1 granite and 2/3 diamond.
Using whirling blades as AoE(or Lighting Strike if Enough STR, IDT I'd use cleave, must see; I could use cleave in close situations tho), frenzy for 1 target and flicker when possible.
blood rage obiously is a must-have since CI is used.
toughts?

Bump, sigthly reworked and starting to play this.
