Hello!
I'm pretty new to assassination (ilvl 383 atm) and abit unsure which stat is the best. When I sim my stat weights mastery comes ahead by about 5% versus crit (2,2-ish vs 2,1). At the same time I see almost all rogues choose "deadly navigation" (crit) over the "masterfull navigation" (mastery). All guides also point to crit being the better of the two stats.
So .. which is the better stat? Does this change alot with azerite traits? Or gear/ilvl? At the moment I got the traits "Twist the Knife", DDx2 (or DDx1 + Trecherous Covenant) , "Nothing Personal" x 2, SS (or +1 DD and Blightborne Infusion).
Cheers.
