Carnage has become a bit more clunky and took a dps Nerf a while back. If you plan on doing ranked, the meta is Fury. Here is the info from the theory discord. (It maybe out of date cause I got booted from it months ago).
Set bonus - Descend of the Fearless; one piece Amplified Champion
Tactical - Cauterized Conary
Amplifier - Armor Penetration or weapon expertise. There was a bit of a debate about this and I believe weapon expertise came out on top. But I’ve seen no definitive numbers
Stats
• Alacrity:
>= 1213, 1.4 GCD *without* Guild Perk
>= 1895, 1.3 GCD *with* Guild Perk
• Accuracy:
>= 1590 (for pve) You only need 105% for pvp
• Critical: remaining tertiary stats
This might also help with what gear to keep and what to destroy
Very helpful post. Thank you. Bummer to hear that Carnage is bad.... Such a bummer because it's by far more fun (at least IMO).
