Deathmark. Medium gain

Do: On the Venomous Heart, build with Mutilate. Use Fan of Knives only with 2 or more targets.
Why: The Heart takes double damage, and inside Deathmark you pressed Mutilate about half as often as top Assassination Rogues.

Burst on the Heart.

Deathmark and Kingsbane went out on both Venomous Heart windows, with your potion in the first.

21k behind a typical Assassination Rogue here, a little on every button. Nothing stands out as one fix.

What happens

Collect eggs and break them in the Spectral Coils soaks (two teams on Heroic). Dodge Caustic Waves, which come from the side of the wing Ula'tek pulls back and spawn a deadly Viper if they hit an egg carrier. After two cycles, Rage of the Shackled exposes the Venomous Heart, which takes 100% more damage for 20 seconds.

You pressed it as often as typical Assassination Rogues. Each one hit about a third softer (696k vs 921k). We haven't found why yet, so there's no fix to give.

Cooldown · ~9kPress Kingsbane when it's ready.

It sat ready from 3:22 to 4:49. Pressed whenever it was ready, that's 7 uses this pull instead of 4. The Venomous Heart takes double damage from 4:45 in this phase. You pressed it 1 time in this phase; typical Assassination Rogues 2.

Your job as Assassination Rogue iThe raid splits to the two side platforms. Kill the Doomscale Warden, break Grasping Fangs tethers two at a time, carry eggs to the Cauldron, and interrupt the Weakened Doomscale's Anguished Cry.

Fan of Knives when the Warden and eggs are near each other; Mutilate when it's just the Warden. Watch the tether breaks: each one puts a raid-wide DoT on both platforms.

It still cost about 12.2M damage the raid had to make up.

You pressed it 0 times; typical Assassination Rogues 1. We haven't found why yet, so there's no fix to give.

What happens

Platforms. Serpent's Bite soaks for melee, ranged, and healer groups, Volatile Purge spreads, Caustic Waves with gaps, and Circling Prey breaking the melee platform. Kill Blightscale Shriekers fast. Ends in a final heart phase.

How you pressed buttons iYour presses on pull 12 compared to top Assassination Rogues on their kills.

Pull 12: 2 things to fix, plus haste and button speed

40 presses a minute vs 45 for top Assassination Rogues, 39 for a typical Assassination Rogue

Why you pressed less

Haste: same as top playersiThe global cooldown is the wait after each instant press. Haste shortens it. This is measured outside Deathmark and haste buffs, so it compares gear, not cooldowns. Many top players also get Power Infusion from a priest.

Your global cooldown was 1.00s, top Assassination Rogues 0.99s.

Long pauses: no more than top playersiTime with nothing happening: no global cooldown running, no cast or channel. Moments when most of the raid's melee also stopped (the boss moved or couldn't be hit) are left out.

4 times you went 4 seconds or more without pressing anything; top Assassination Rogues: about 7. At 1:33 (6s), 3:26 (24s), 4:05 (6s), 5:33 (4s). Worth a look on your video: moving, a mechanic, or out of range?

Button speed: about the same as top playersiHow quickly each press follows the last when you're not moving: within a quarter of a second of the global cooldown, cast or channel ending counts as on time. For energy specs, waiting on energy counts as a pause too.

84% of your presses came right as the last one finished (top Assassination Rogues 80%). Short pauses add up to 7.2s a minute (8.7s).
