when there is like 20 loot for each boss, certain item drop has such low drop chance for 10 man
I play shadow priest and just to let everyone know how UNLUCKY I am on trinkets (currently im ilvl 572, every item heroic except BOTH trinkets)
Immerseus trinket -> 15 kills on heroic (dropped once, our elemental shaman got it)
Immerseus trinket -> 15 bonus rolls used on heroic (almost got every item TWICE for shadow spezialation, but no trinket)
Korkron Dark Shaman trinket -> 12 kills on heroic + 12 bonus rolls on heroic = no trinket (0 actual drops so far)
currently running with Garrosh normal trinket and Lei Shen Normal forged
Looks I'll replacing them with WoD greens.....
