Hi everybody,
I have some questions about stuffs Best in Slot for Rogue Assassination.
In the guid written by Fury in this link (https://www.icy-veins.com/wow/assassination-rogue-pve-dps-gear-legendaries-best-in-slot).
He said for head and Chest, you should choose these items:
Helm: Fanged Slayer's Helm
Chest: Hide of the Abyssal Behemoth
But I chose these items, because when you see characteristics and calculate them, it’s better (see below)
Helm: Lunar-Wrath Headgear (boss: Sisters of the Moon)
Chest: Fanged Slayer's Chestguard (Maiden of Vigilance)
In each item, you got Mastery and it’s the second best characteristics, but in items suggest by Fury you don’t have Mastery.
If someone could explain me, it would be graceful.
Stat priority:
1)      Agility
2)      Mastery
3)      Versatility
4)      Critical Strike
5)      Haste
Thanks,

Here on Icy Vein's under the Arms Warrior DPS guide here is the recommended relic choice. I was under the impression that [Exploit the Weakness] was our top priority even if it meant 20-25iLvl difference. Since it would increase the proc chance by a factor of x2 with all three relics increasing Tacticians...
Why does this guide on Icy Veins say otherwise? Is it because the information is out of date and hasn't been updated?
 
(Original Link: https://www.icy-veins.com/wow/arms-warrior-pve-dps-artifact-talents-traits-relics)

 
Unfortunately this is not someting I can just run a Sim on because I don't currently have any [Exploit the Weakness] relics.
