Hello. I would like to talk to you about such things as Grongs trinket RAGE trinket (Mekkatorque). Your addon does not correctly use them in the rotation. Because as I looked they are used by more experienced people according to such tactics.

When should I use the Grongs trinket?
Pretty much off Cooldown. Use it in the opener after you've popped Unholy Frenzy (wounds will still be applied).

How do I use the RAGE trinket (Mekkatorque) correctly?
Use it in opener and use Unholy Frenzy as you usually do. Then save Unholy Frenzy for your other uses, popping Unholy Frenzy 6 seconds after using the trinket.

And it turns out that these conditions Hekilli does not take into account. And it turns out in fact that I immediately give away at all two trinkets. Is it possible to implement them in addon so that he understands when to use them? I have not found where I can set these conditions as described above. And also when changing the race, hekilli does not show to use the racial abilities of another faction (Berserk, etc.)

Unholy DK should talk to their simc devs about including this in the Unholy priority.

You can absolutely add/change this in your own priority if you want.
