Anyway to the OP,
License to Slay and Vessel is the best combination from the trinkets you mentioned. Never use the Essence as Unholy, it's a horrible trinket unless you are in a Frost spec and you line it up with Pillar of Frost and make good use out of that 15-20 second window of high burst. However Vessel is not all that good of a trinket. Do you have access to a Heart of Rage normal? If you do use that one with License to Slay. I would highly recommend trying to find a group/pug to do Chimaeron with and hope you win that trinket. It's really good and you'll use it for a long time.
