I got Mistcaller Ocarina from an M+ earlier and BiB is suggesting a 146 blue instead.
I thought that was odd so I looked in the Wiki and can’t see the trinket in there, or I’m looking in the wrong place, so BiB doesn’t have enough data to optomise around it.
I also learnt that you can change the stat it gives by purchasing the relevant item from Master Clerk Salorn, I changed mine to crit.
Apparently you can get multiple buffs from people in your group, not the whole raid, as long as they aren’t the same secondary.
