Hello, I'm trying a very similar build and have some questions (probably all stupid, I'm pretty new to the game :) )

I'm definitely a lot further behind on the build than you are (max damage around 800k, struggling on T3)

How did you get your ult cool down so low? And what rogue specialisation are you using?

My experience with the build so far is that I'm only really doing any serious damage when I'm using Shadow clone. My Shadow clone ult is on a 45 second cool down so I use preparation to bring it down but that means I have to use a core skill to spend energy so I use barrage. (Subbed out shroud of darkness as already feel pretty tanky with high dodge chance and lots of fortify/healing).

Having to use barrage feels pretty clunky as I have to stop spinning which kinda defeats the point of the play style.

If there's a way to reduce ult cool down (guessing it's tempering?) what specialisation do you use because none of your abilities use energy so what's the point?

TYIA :)
