*DW frost*for my calculations.

RPPM system details for reference:

Below are the scary guts of the new trinkets and metagems. This information is for theorycrafters. You don't need to read this to understand how the mechanics work or enjoy their benefits.

Trinkets

Strength DPS

- Brutal Talisman of the Shado-Pan Assault - 15% chance on landing harmful abilities and spells, and melee/ranged abilities and swings. 75 sec ICD.

Trinket rankings (all done with 522 ilevel version):

Brutal Talisman of the Shado-Pan Assault: 1467 expertise * 1.8 = 2640 (you're going to be expertise capped with or without the trinket, and this value is the best case scenario, assuming you can reforge it all into mastery (expertise elsewhere). In all likeyhood, it will be closer to 1500) 8800 str for 15 seconds, with ~ 82 second intervals, 1610 static strength * 3.67 = 5907 + 2640 = 8547 dps

Fabled Feather of Ji-Kun: 1467 hit * 1.8 = 2640 (you're going to be hit capped with or without the trinket, and this value is the best case scenario, assuming you can reforge it all into mastery (hit elsewhere). In all likeyhood, it will be closer to 1500, or even 1k considering how much hit we have) "Your attacks have a chance to grant Feathers of Fury, granting 1333 Strength every 2 sec for 20 sec." Assuming the first proc starts at t=0, by t=18 the proc will be at 13330 strength, for an average of about 7331.5 strength * 3.67 = 26906. 0.56 rppm * 1.5 from melee haste = 0.84 ppm, 22601 with 1 ppm/4 = 5650 (with 1 ppm and 20 second uptime, and a 22 second ICD, it will proc once every 80 seconds on average, giving it a 25% uptime) _ 2640 = 8290 dps

Primordiusâ€™ Talisman of Rage: 1467 crit (587 mastery* 1.8=1056.6/880 crit*1.39=1223.2, reforged to mastery) = 2279 dps. Your attacks have a chance to grant you 1538 Strength for 10 sec. This effect can stack up to 5 times. 3 ppm * 1.5 meleehaste = 4.5 ppm, 75% uptime baseline * 1538 =1153.5 * 3.67 = 4233 dps, however each time a proc is overridden, the duration of the last proc is effectively extended to back to 10 seconds. There is a 75% chance of this happening each proc, with an average extension of 5 seconds, or 3.375 ppm with an uptime of 5 seconds, 16.875 extra seconds a minute, 28% uptime * 1538 * 3.67 = 1587 dps. 8099.5 dps

Spark of Zandalar: 1467 haste (587 mastery* 1.8=1056.6/880 haste * 1.65 = 1452, reforged to mastery) = 2508 dps. Equip: Your attacks have a chance to grant you a Spark of Zandalar. Once you have accumulated 10 Sparks, you will transform into a Zandalari Warrior and gain 7333 Strength for 20 sec. 5 rppm * 1.5 meleehaste = 7.5 ppm, 20 sec duration 0.75 ppm of actual buff, = 25% uptime, *7333 strength *3.67 = 6728 dps + 2508 dps = 9236 dps.

Gaze of the Twins: 1467 str * 3.67 = 5383 dps, Your critical attacks have a chance to grant you 2868 Critical Strike for 20 sec. This effect can stack up to 3 times. Following calculations work if you get 1 crit every 10 seconds, or more often, 1 ppm * 1.5 meleehaste = 1.5 ppm, 50% uptime baseline * 2868 crit * 1.39 = 1993 dps, however each time a proc is overridden, the duration of the last proc is effectively extended back to 20 seconds. There is a 50% chance of this happening per proc, or .75 times per minute, and the average extension will be by 10 seconds, or a 12.5% uptime, worth 500 dps. 7874 dps total.

These calculations were done before the change to the way the proc worked. It will now be slightly better with about 25% melee crit, slightly worse with below 25% melee crit, and the same with 25% melee crit. First look suggests this won't change ranking order.

I would personally rank them in this order:

Spark of Zandalar

Primordiusâ€™ Talisman of Rage

Gaze of the Twins

Brutal Talisman of the Shado-Pan Assault

Fabled Feather of Ji-Kun

Legendary Metagems

Capacitive Primal Diamond â€“ 15.00 base RealPPM on landing melee/ranged abilities and swings. No ICD. At 5 stacks, fires Lightning Strike, which deals [280 + 75% AP] Nature damage. That base proc rate is multiplied by an additional coefficient by spec:

- Frost DK (2H): 1.309

- Frost DK (DW): 1.572

- Unholy: 1.34

Note: For DW frost, the legendary meta is worth about 5k dps in current gear. I'd imagine it's somewhat close for all specs. However, the cost of losing the normal meta gem is 2k, and I can't find the post I thought I read saying you get to keep both, so it's possible I'm crazy and that the net gain is 3k.

Meta gem value calculated by simming a full BiS DW setup with and without the meta gem, 2159 dps loss.

Legendary meta calculated for DW by using base AP of 48k, assuming procs will bring average ap to around 60k, 60k*.75+280=45280 dmg per proc.

15 base rppm*1.572 DW modifier * 1.5 melee haste modifier = 35.37 ppm/60 = 0.5895 pps/5 procs per hit = 0.1179 hits per second = 5338.512 dps * 15% meleel crit chance = 6139.29
