Thanks for the detailed analysis. Next please tell us about your really cool set of spirit gear that you just know will make your DPS skyrocket, because it just will.
Ive already got a set of gear that will give 59% armor penetration with raid debuffs at all times using a axe/polearm. I just need grim toll to finish the set and make it work. I didn't calculate how much i would get out of grim toll but the proc must give me close to 100% armor penetration if it doesn't. This would skyrocket dps versus any other trinket.
