What you wanna do is to equip as much mastery gear as u have. After this, is that on pull what u wanna do exactly is -
Pre-pot>Chaos Blades>Equip your normal gear>Meta>And then go fucking ham!
I have 42% increased damage from CB with my Mastery gear.
Been pulling burst numbers close to 3M in single target encounters with this.
Been searching some for this and i have noticed that this is not a known thing it seems like so im giving all my DH brothers out there this tip while it still works, this is not obviously intended to work since the snapshot system is removed, so why this is working is beyond me.
They fixed rogues slice and dice but it seems like this is not known to Blizzard atm.
It might be threads about this already here, but didnt cba to search for it so i just made this thread
So be sure to use it while it works, big fun!
