Assasination relic question

[Borgeus 0]

Hello all rogues in Azeroth. I'm a 915 assasination rogue. Can pull 1,5m burst dps and substain around 700-900k dps during longer fights. 
Since my question is about relics I don't feel the use of armory and logs to answer my question. 

My weapon is ilvl 920 and I feel it's falling behind with my raidpartners and I'm thinking of when to switch out what I'm using. Since I'm using two master assasin + boots my vendetta is on around 45 sec CD
I have: 
shadow: 905 toxic blade relic.
Iron: 885 master assasin relic.
Blood: 900 master assasin relic.

Should I focus more on ilvl with for example Iron-relic? 

See you around and remember. If someone scary comes. Vanish, shadowstep, Mutilate

Hey there.

Last time I checked 2/3 MA relics with CoF trinket and Leg Boots were still doing quite fine. Weapon dmg is not that important for Sin rogues so the higher ilvl relics don't do that much different unless it's of course by a bigger margin.

If you want to change your relics though and go for some higher ilvls you should also swap your Leg Boots (assuming you use CoF). Currently I sit with 1 MA relic + CoF making Vendetta line up with every second KB. This gives me the opportunity to use Leg Wrist instead of Boots - giving me a significantly burst in the execution phase (super powerful on FA for instance). Also note that in progression type of raids bosses usually die way slower giving the Leg Wrist a pretty good advantage.

Thank you for the advise. 
Since I have all assasin-locked legendarys + neutral legendarys except Sephuz and the empty crown I usually use 4p + wrist and boots. 
I have a CoF 900 with trinket. 

When doing WQ and lower keys(where I expect the mobs to die pretty fast) i usually use 4p + shoulders and boots. 

The difference is 15 ilvl for the relic without any warforged or titanforged. 

I try to use vendetta + KB every time. Sometimes I have to wait for KB, sometimes for Vendetta. Usually not more then 5 seconds. 

My raidteam are progessing in heroic ToS. We are having a break and sometimes do normal ToS. Next week I hope we start working on progession heroic again. 

If it's ok with you I will ask to get logs for today and I link my armory later(3-4 hours). I know I need to work on keeping up rupture, but sometimes it's hard when you are 10 feet away during different phases.

Unless it's an overwhelming improvement in weapon ilvl or trait (i.e getting rid of a Cloak trait for a Vendetta) relics should be the absolute last thing you change, since there's no going back.  Creative stat balancing can help out to an extent - if you only have 1 Vendetta relic, for example, you could try stacking more crit to offset the dps loss somewhat.

I couldn't get logs today, and also we did a fun run through heroic nighthold. 

Here is my armory if someone would be interested to see what I can improve. Mastery should be higher, I know that.

If the gear doesn't change until you look at it(it shouldn't), this is my "burst AoE focus on ST gear" for fights with no AoE I change umbral moonglaive for Infernal cinders 915.
