Ok,I've missed BL, in my memory warcraftlogs for some reason did some blueish background for the time BL/heroism/timewarp was active,that is no omore, maybe I had a dream or had something selected
A fast look over Sub rogues up to ilvl 679 not effected by MoS bug and with a similar combat time provided me with this:
(Just a little reminder, I'm pretty bad dps wise, just trying to provide theoretical advice, I think you are doing very good)

I'll compare this to your log here:
https://www.warcraftlogs.com/reports...uras&source=13
I know there might be better, but this is the best base for comparison.
Just like you want, he is doing over 40k. His Burst is over 100k,but he focused everything on the burst.
You both had Timewarp/Bloodlust at the start, you did not prepot
He also had Lucky Coin, not the best trinket anymore but still great for he burst and he used it with every SR.
Seems like he clipped 1 or 2 seconds FW with his first vanish (dunno of it is worth it for increased dmg for first ambush) giving him another Master Ob Subtlety while having TimeWarp and also increased his initial FW uptime from start of combat to 31 seconds after, all increasing the value of TimeWarp.
He also had awesome look with Scales and Legendary Ring Procs, all fitting the initial phase.
You should also use your first Vanish right after FW after SD falls off.
You may compare your Vanish use vs. Find Weakness to yours.

Even as Troll you also should have used Vanish three times,not only twice. Do not forget to use
preparation right after first vanish use. In a patchwerk fight like Gruul you should not have any other use for it other to reduce Vanish CD I think?
Well, he also had a FW uptime of over 68%, but this is also to him/her beeing nightelf.
If you are really focused on maxing your dps you also might shadow step sooner.
He did garrote combat 378 ms after pull, you ambushed (I think you should use garrote and then ambush when using subterfuge) after 1.5 seconds. (just noticed, you did sprint, maybe no Shadowstep skilled?)
Hope this helps in some way? This is all meant in a positive way, not criticizing your way too play, like I said I'm doing much worse.
