This is a fairly common question I see asked around the internet. Unfortunately most trinkets behave in unusual ways that make them difficult to evaluate using simple math and spreadsheets. On top of that the typically provide a large quantity of a single stat and therefore can sckew the results of a typical valueation.
So, what's the answer? Throw it in SimulationCraft and see what it says.
Honestly , I don't have much of a theory on this one. I've made several statements about the valuation of trinkets over the past few months and they seem to change with each statement. You may remember back to my first ICC gear list I said the two Reign Trinkets would remain BiS. Well I am now sure that I was wrong then.
I was wrong because I didn't take into account the amount of Spell Power I would be picking up by upgrading to T10 level gear. That dramatically helps Crit and Haste but has little impact on the proc value of either Reign trinket. Don't get me wrong. Both Reign trinkets are still very good trinkets in ICC, but I think the ICC trinkets are giving them a little more competetion then I first expected.
What SimulationCraft Says:
As usual, I used myself as the example. First, I assumed two base level trinkets: [Illustration of the Dragon Soul] and the normal [Reign of the Unliving]. I realize that not everyone has had luck gaining these trinkets, but Sarth and ToC are very pug able. Therefore I don't think they are out of the realm of possibility to be concidered baseline trinkets.
After I established a base level of DPS I started to exchange the IotDS for the DPS trinkets available from ICC10 and ICC25. In the table below are all the DPS values I got from SimulationCraft for each trinket.
|Dislodged Foreign Object (H)||11,216|
|Reign of the Unliving||11,210|
|Phylactery of the Nameless Lich (H)||11,201|
|Phylactery of the Nameless Lich||11,131|
|Dislodged Foreign Object||11,123|
|Muradin's Spyglass (H)||11,099|
As you can see the Heroic 25man trinkets all did very well for me. Even the Heroic version of Reign of the Unliving was comparable to Heroic DFO and Heroic PotNL. I am a little surprised with how low both Spyglass trinkets were. I thought the heroic version would at least be a little higher upPlease, do not take this as a definitive list of which trinkets are better then the others. If I ran this in a month with different gear it might be different. I highly suggest that you try running theses through SimulationCraft for your own toon.
Do It Yourself:If you don't have it already, you can download SimulationCraft from here.
After you have it downloaded you want to make sure it is set up correctly for you to import your toon, and assume all of the correct buffs. Click the Options tab at the top. You should see several more tabs appear below it. Click the Global's tab and make sure it is selecting the lates patch and make sure that the Armory region is set to your region. Then, if you are with the Alliance, go to the Buff tab and make sure Heroic Presence is checked.
From here it is fairly easy import your toon. Go to the Import tab and search for your toon on the armory and hit the import button. You can also import your toon from WoWhead or Rawr if you use either of them. After you click the Import button it will populate the Simulate tab.
Here is where it gets manual. In the middle of the import your gear will be listed. Towards the bottom of your gear there will be two lines for Trinket1 and Trinket two. These are the lines you want to replace to evaluate new trinkets. Here are the lines for the trinkets I used in the post:
If you are familure with WoWhead or Rawr it is much easier to change the trinkets with those tools and reimport the file.
