Sup everyone so looks like Grievous proc trinkets arent getting the bonus from unholy might check these screen shots i took from in game.
this is my toon's strength with no buffs with no trinket proc in stormwind
this is him with the grievous trinket proc in stormwind.
this is my strength in a battleground with no trinket prc
this is with trinket proc in a battleground.
So as you can see when im in stormwind im getting 6798 strength when my trinket procs.
When im in a battleground im only getting 5386 strength.
