Trying to find some help, was going to try on ravenholdt but it appears the forum is basically dead at this point.
A little background to begin:
I've played nothing but Mage from vanilla up until the first tier of cataclysm. I recently rolled rogue since my friend's guild didn't have one, and resubbed a couple months ago. I've had a ton of issues adjusting to melee, but I've finally gotten to a point where I'm comfortable and ready to nitpick everything about my performance. The guild just started mythic mannoroth progression ~2 weeks ago, and I'd like my performance to increase so we can hopefully kill this thing this week.
I only have a couple logs to list since a lot of what I learned initially about sub was apparently incorrect, but here are two in which I'm up to speed with the boss mechanics:
iron reaver:

kilrogg:
https://www.warcraftlogs.com/reports...&view=rankings
To explain my understanding as of right now:
Opener is extremely important. I'm following Rylix's guide for the opener, and now trying to not overcap CP by weaving in eviscerates with 5 CP(had initially read just to ambush spam...).
Goal is for 100% rupture and SnD uptime(missed on this goal in those two logs)
Pool energy/CP for soul cap procs and for shadowdance
Use vanish on CD unless there's <6s between it and SD, or <12s for SD+ring(previously under the impression of matching vanish CD with SD cd)
I understand I should be using premed more often, but I feel like every time it's available I end up being CP capped anyway off ambush... help on that would be appreciated.
On the fel reaver attempt, I had an extremely similar kill time to the top ranked rogue for my ilvl, so I looked at our comparison
Biggest discrepancies: He had 21 ambushes vs my 13. Obviously I messed something up here. I may not have pooled energy correctly on my second shadowdance and/or vanish. I also noticed he got a 4th vanish off, seemingly due to more ruptures and eviscerates lowering the CD. This also explains why I have more backstabs, as I was using GCDs on it instead of more eviscerates/rups(although I think his 12 rups was excessive)
Neither of us had 100% rupture uptime, but I believe this is due to not killing the boss before air phase.
Aside from that, the absolute biggest damage discrepancy seems to be that I messed up a trinket proc, not cancelling it correctly for the first ring, resulting in a colossal 3 million damage difference just from the ring, in addition to the likely lost soul cap damage. There was an issue with my cancel aura macro which I have since fixed.
Any tips are appreciated, especially for mythic manny on subtlety- my guild has a ton of aoe so imps are a non-factor, thereby I'm going sub to nuke the doomlords. I've struggled a ton with my DPS on that fight, and I think I may need to swap to a hemo glyph for all the target switching I'm doing on it.
If you want to look through the rest of the logs to assist, feel free. The reason I listed these two is simply because the other fights I'm not particularly clear on positioning due to only having a couple pulls on them(kormrok... let's not talk about that). Positioning and GCD management has been my biggest struggle thus far- compared to my mage, I often felt lost in melee position and unable to discern mechanics from other effects, I also found it hard(and still do to some extent) to realize when an ability has been executed since there are no casts bars and I'm so used to having one.
