I play both spec and just looking to see what I should sepnd my 2nd dinars on
For trinkets I have
Improvised Seaforium Pacemaker heroic track
Mechano-Core Amplifier heroic track
Ring
Ritual Bone Band Heroic track
85-Year Tenure Ring mythic track
Weapon for prot
Everforged Longsword ilvl 681 crafted
G0-4W4Y Crowd Repeller heroic track
ret
Capital Punisher heroic track
I don’t do mythic raid so getting mythic track items with dinars is out of the question.
I could get a The Jastor Diamond ring in heroic track or better trinkets. But since I play both spec I don’t see other trinkets that will be good for both spec. Both of my trinkets are pretty passive so works well with both spec. I could get a Eye of Kezan or House of Cards heroic track but it seems Eye of Kezan is meh for me while House of Cards the on use effect is really good… But is it worth it since both trinkets I have now are still pretty good.
I could also get the 2handed mace Best-in-Slots in heroic track or for port get the shield Titan of Industry heroic track.
All the upgrade seems ok just hard to pick one…
Dinars really overall depend on what content you expect to be playing (and enjoying)
M raid is inaccessible to many people, and you said that was right out, so while getting a H track Jastor Diamond may be nice in the moment, you may be able to get a Myth track ring of decent stats from other sources (And, full disclosure, the H track Jastor Diamon may even sim slightly higher, but it’ll feel real bad to buy with Dinars something that you can fill instead with weekly vault)
Because you do both Prot and Ret, a M track Seaforium Pacemaker would be good if you can get all 12s timed (and if you play Prot tons, a M track Tome of Light’s Devotion will give you good milage)
You can also use Signet of the Priory on Ret in M track from all 12s if you don’t want to use a H track House of Cards (like I did)
Because your weapon is already crafted on Prot (and you can use the ascendance embellishment) its probably not worth it to try and join a M Pug for first [starting Rik] to get access to Remixed Ignition Saber
Overall, id do some soul searching to see if you want to get all 12s done
Jastor on hero track is good. In a lot of the sims I run it’s been amazing. It sims higher than some of the mythic track rings I have. Timing 12’s gets you access to BiS trinkets. Pacemaker is a must. Signet is also really good for ret.
I got heroic tomb when I did a +10 today. Going to wait for the value friar and hope for the mythic tomb so I can spend the dinars in ret spec
Be careful with your sims. The tier lists floating around can be misleading on WoWhead as most of them are mythic raid/+10 focused. As Yekal mentioned, it depends on the content you are progressing in.
If you have ever heard of the site Bloodmallet, there are advance options to restrict item levels based on which track they perform better in. For example, a maxed out Hero level Suspicious Energy Drink plus Mechano-Core Amplifier out performs a hero track Pacemaker at 671 ilvl, but the mythic Pacemaker at 681+ outperforms the other two.
Simming your character through Raidbots should also tell you what upgrades to get based on the content you mainly focus on.
Both of those are ranked higher on WoWhead over trinkets like Mythic Signet of the Priory. They’re very good trinkets.
