Mage/Dark Wizard Is this build good or do i just suck

I was lookin for a build that didnt use mythics (cuz im broke :P) and my friend recomended this one he found to me:

https://wynnbuilder.github.io/build...1a-q0l-q1g000010009I0z0z0+0+0+0+0-1TzZdsgrMZ5
WynnBuilder build:
> Brainwash
> Discharge
> Asphyxia
> Ornate Shadow Cloud
> Intensity
> Photon
> Enmity
> Simulacrum
> Event Horizon [w6w6]

Ive playing with it and it seems okayish i just feel worse then other players and not super powerfull. IDK im not a build guy just wondering if its me or my gear

 

that's a good build, it's the best you can get without going into mythics for now, I'd suggest making sure to keep heal uptime and recasting meteors if any orbs die, avoid getting hit too, and keeping ur distance to make sure ur lightweavers hit the enemy
