I am asking this question for both MM and BM. I mainly play BM in dungeons and raid as MM.
So I got two world quest trinkets. Both with 1123 Agility and 898 Mastery. Considering our stat priority for both specs is Agil>Mastery I've been mainly sticking with them. But after running a god awfully large amount of Mythic+ I got a few trinkets, but unsure if they're better, and if it actually makes a difference for trash.
I now have two 845 trinkets. Naraxas' Spiked Tounge and Tirathon's Betrayal. Now I figured for killing Dungeon bosses and Raid Encounters I will switch to these? but for trash packs in Mythic+. Will my pure stat Agil+Mastery trinkets be a better choice for killing the packs faster for BM?
