Need opinion on my build(Crit DualStrike+Cyclone)

Hi guys.

So I am trying to work on my own build but I want to ask if some of you could give me any opinion or advice since I dont really know much about the game yet(3 months experience).

My main skills would be: Dual Strike for single target and Cyclone for AoE.

Gems: Dual Strike 4L: Dual Strike+Life Leech+Faster Attack/Multistrike+More Physical Damage
Cyclone 5L: Cyclone+Blood Magic+Faster Attack+Life Gain on Hit/Life Leech+More Physical Damage.
Vengeance 3L: Vengeance+Endurange Charge on Melee Stun+Stun
Auras 4L: Haste+Herald of?
Utility/Defensive: Molten Shell+Whirling Blade og Leap?

The defensive part in this tree would come from HP, all res and life leech for survivability. The offensive part would come from: Crit, attack speed and increase physical damage.

I would like to know if I should change the skill gems combination or rework my passive skill trees? Any help would be very appreciated.

Thank you.
