Legendary shoulder is also a big deal. With shoulders and a few gutripper relics, u can start losing some crit in favor of mastery and vers.
Gameplay wise, try to keep nightblade uptime at 90% +. I notice alot of times you only have enough energy to shadowstrike twice after your DFA, that might because you had to cast backstab 3-4 times after you symbol to build up cp, as a result you are energy starved after the dfa. Try to have 60+ energy before you dfa, meaning casting symbols to recover energy after you build to full cp (sometimes u may have to pool for a sec). For now, since you don't have shoulders, I would delay your vanish in the opener until master of subtlety buff runs out so you don't overlap the buff from vanish. After that use it on cd for the extra shadowstrike and buff.
