The Black Heart & Essence of Gossamer
I have a fairly limited selection of tanking trinkets, all are from 5 mans or emblems;The black heart, Valour medal of the first war are my usual choices for raiding, with seal of the pantheon/Lavanthor's talisman as my block gear ones.
Now i tend to feel fairly squishy in raids unless i have a pally or shammy healing me, but i can't be fussy about who heals me, so if a i'm being healed by disc or a holy priest, is it worth switiching the medal for the essance, i'm sitting around 43K raid buffed, 33K unbuffed, i'd lose about 1.3% dodge but gain the 111stam, which one will help my healers more?
