I prefer Unsolvable Riddle as well. I absolutely hate it when I see my trinkets proc two seconds before a movement phase, they're put back on ICD, and the procs are wasted. In my experience, being able to control when and where TF/Berserk, Potion, Trinkets align is almost always a DPS increase.

This is probably true for 10man raids where you only have a limited amount of interrupters. But especially in 25s you should not put a feral on interrupts, since ferals have probaly the highest dps loss from interrupting. Rogues can get a 5 energy kick with the PvP Gloves while ours is at 25 (15 with gloves) and they generally have alot more energy to play with. Shamans interrupt is practically free unless they are mana limited, and for example DKs use a secondary resource that is not responsible for 75% of their damage.

I just read that we don't need expertise for our kick because mobs cant parry or dodge while casting. Can anyone confirm this?

I was going over the trinkets with Rawr that was heavily pushing the Str proc trinkets. I noticed that Rawr says that the procs are every 45 sec. From what I can tell, that is never the case. I believe that the proc cooldown is 5/6 downtime. So, if the proc lasts 15 seconds the downtime is 75 sec, meaning it's up 15/90 seconds optimally. If it's a 20 sec proc it's 20/120 seconds. This significantly changes all the trinkets for me. I did some minor theorycrafting based off my current stat weights based off Mew's results.

Does this seem right?

There seems to be a lot of confusion about which trinkets are the best. This is the equation you can use to determine your value of just about any trinket in the game.

<static_stat> * <stat_value> + <proc_stat> * <proc_value> * <duration> / ( <internal_cooldown> + <time_to_activate> )

It may look a bit complicated, but here is how it breaks down:
eg. Skardyn's Grace (346) - 285 agility, Use: Increases your mastery rating by 1425 for 20 sec. (2 min cooldown)

285*<value_of_agility> + 1425*<value_of_mastery>*20/(120+0)

This assumes that you use this on-use trinket as soon as it comes off of cooldown, which should give a good approximation of the value. I'm going to sub in some values for the stats taken from TheJinchuuriki earlier in this thread to make things a little easier.

Skardyn's Grace (346)
285*2.7 + 1425*1.03*20/(120+0) = 1014.125

Now the same thing can be applied to a proc trinket. It's just slightly more complicated since you may not know the internal cooldown or the average time to activate the proc. I'll be using estimates for these, although it should be pretty close in practice. For all trinkets, wowhead will have a link to the spell proc, which shows the actual proc % (can sometimes be wrong for ppm items, but there are very few of those at 85). In most cases, the internal cooldowns have already been tested and are listed in the EJ Rogue forums. They are also usually noted in the wowhead comments. If you can't find the cooldown for a trinket, assume it's 5x the length of the proc.

Key to the Endless Chamber (346) - 285 Hit Rating, Equip: Your melee and ranged attacks have a chance to grant 1710 agility for 15 sec. (10% proc, 75 sec Cooldown)

285*<value_of_hit> + 1710*<value_of_agility>*15/(75+<time_to_activate>)

What is the time to activate? Since this is a 10% proc on any melee attack, we need to calculate the amount of time it takes for our cat to attack 10 times. I took a slightly conservative estimate and said 8 seconds (8 auto attacks and 2 yellow attacks). So substituting the correct values:

Key to the Endless Chamber (346)
285*.63 + 1710*2.7*15/(75+8) = 1013.94759

That calculation does not include any reforging, which is an option, since the static value is a secondary stat. So recalculating after we reforge hit to mastery:

Key to the Endless Chamber (346)
(285*.6)*.63 + (285*.4*1.03) + 1710*2.7*15/(75+8) = 1059.54759

This should provide the basics for anyone who wants to try and evaluate their own trinkets, but there are still some that may need further explanation.

eg. proc based on a crit
Left Eye of Rajh (346) - 285 Expertise Rating, Equip: Your melee and ranged crits have a chance to grant 1710 agility for 10 sec. (30% proc, 50 Sec Cooldown)

The only significant difference from the Key calculation is that now you need to know how long it will take you to get ~3 crits. If a third of our attacks are crits (~33% crit), then that will be 9 attacks. As crit % goes up and haste goes up, that number reduces. I'll estimate 6 seconds as a time to activate. And to save a step, I'll include reforging to start out.

Left Eye of Rajh (346)
(285*.6)*.63 + (285*.4*1.03) + 1710*2.7*10/(50+6) = 1049.614286

Another very popular trinket right now is Tia's Grace. This is a bit more difficult to calculate, because it has an uptime type of proc rather than a duration and proc chance. Here is the calculation that I used for it.

Tia's Grace (346) - 285 Mastery Rating, Equip: Your melee and ranged attacks grant 34 agility. Lasts 15 sec, stacking up to 10 times.

Considering that it is 100% proc on any attack, I can assume that I'll be attacking at least once every 15 seconds on the vast majority of fights, so I'll use 100% uptime. But, since it's a stacking proc, you also need to consider ramp-up time. I've chosen to ignore this, because the ramp up time should be 8 seconds or less with our <1 second attack speed. 8 seconds out of a 5 minute fight isn't really significant to me, but if you wanted to include that, 8/300 = 97% at full efficiency which will be closer to 99% when you add in the partial stack values. I'm just going to use 100%.

<static_stat> * <stat_value> + <proc_stat> * <proc_value> * <uptime> * <ramp_up>

285*<value_of_mastery> + 34*10*<value_of_agility>*<uptime>*<ramp_up>

Tia's Grace (346)
285*1.03 + 34*10*2.7*1*1 = 1211.55

I hope this helps as a good primer for anyone still wondering about trinket values.

Oh, and using the stat values quoted above, the BiS trinkets are:

Fluid Death	1279.4
Essence of the Cyclone (372)	1265.5
Prestor's Talisman of Machination (372)	1255.6
Tia's Grace (346)	1211.6
Essence of the Cyclone (359)	1119.1
Prestor's Talisman of Machination (359)	1110.4
Darkmoon Card: Hurricane	1070.9
Tia's Grace (333)	1069.6
Key to the Endless Chamber (346)	1059.5
Unsolvable Riddle	1052.9
Left Eye of Rajh (346)	1049.6
Unheeded Warning	1029.6
Skardyn's Grace (346)	1014.1

*Note: Don't take that list as pure gospel. All of the values were calculated using the same equations and stat values listed above, but there are a few outliers that I'm not sure if my calculations are completely accurate. Specifically, Darkmoon Card: Hurricane and Unheeded Warning could go up or down depending on exactly how they're calculated and would be better off if determined by a simulaton.

<edit> I should also point out that I used a lower strength value than is likely realistic, so none of the strength trinkets are included in this list.

We will have to see how what makes live and the full fallout. With damage shifting from bleeds to direct damage, the relative value of hit/expertise and 4t11 will be going up, with mastery and 2t11 going down.

Also, I imagine the changes to OoC aren't going to effect us, but it might be worth looking at some logs to see if it will proc off thorns, fff, nature's grasp or yellow attacks.

I know that, but I have also had time that I simply could not refresh dots until they fell off. Presumably from some other proc.

The only time this happens anymore that I'm aware of is if you try to overwrite a Rip with a lower CP version of Rip, like if Artamedes is taking off and you tried to drop your CP on a lower CP Rip.

Definitely happens with Tol'vir (agility) potions and rip as well.

Trinkets (+agi proc), Tol'vir Potion and possibly TF seem to cause this as well. Not 100% sure on Tiger's Fury as it might've been either of the +agi proc trinkets interfering instead.

I think your undervaluing the on-use trinkets, mew claims [Unsolvable Riddle] is worth much more(~800 dps) than [Tia's Grace]. Face-value conversions fail to accredit stacking on-uses with TF, Berserk or any other cooldowns.

EDIT: As later corrected, I failed to move stats correctly. A second look shows:

with no trinket
DPS: 19389.55237

with Tia's
DPS: 20656.45709
(+340 agi and 285 mastery)

with Riddle
DPS: 20494.52522
(+321 mastery and checked buff on mew trinket list)

So with non-fail entries, Tia's does seem better than Riddle.
