DBW and unholy dk

Deathbringer's will is actually HUUUUGE for unholy dk. So here's a few things to mention:

1). Arpen is an amazing stat for unholy dk that affects about 70% of it's total damage output (even though not 70% is physical damage, much of the dmg is magic damage based off physical damage factors such as scourge strike). Haste is arguably a much better single target dps stat however crit is by far the #1 stat for unholy dk when it comes to doing your job (AOE).

2).
Dwarf crit proc is not bad as your scourge strike benefits tremendously from crit (scourge strike benefits from "Viscous strikes and Outbreak") making the crit scaling on scourge strike quite high. That means that, yes you don't get an insane proc for gargoyle, however you do gain a massive proc for all your skills and abilities. A dwarf proc at the start of the fight is not the worse thing ever.
-Dwarf crit proc on the 2nd proc mid-fight is bad as you save your gargoyle's CD for 30 seconds (105 + 105 = 210 = 3.5 minutes, 30 seconds of holding the gargoyle CD to synchronize it with a DBW proc, 2nd potion of speed, and 340 engi gloves) just to get dwarf proc, you have no additional CDs to push out more scourge strikes and benefit's from the added crit as E.R.W is on CD still.
-Dwarf proc is the BEST AOE PROC in the entire game. Crit is the #1 stat for unholy dk in instances where it can AOE. Haste does NOT benefit diseases or sustained aoe dps for unholy dk. In fights that you are to dps under aoe you'd rather take crit over haste.
-Dwarf gives extra crit, which with the haste given from potion + gloves + bloodlust at the start of the fight, should benefit you quite nicely.

3). Haste = Single target dps
Arpen = Single target dps
Crit = Aoe dps

We all know taunka proc on DBW is #1 all the way, strength is king.
Between the vyrkil and the dwarf proc however, dwarf proc is only bad on 2nd proc of DBW, not first. However it's still the worse proc in single target dps situations, not not by much.

o k ? Pretty sure that "DBW is a good trink for dks" has been established for 10 years now.

As someone who tryed and did everything there is to rest in piece DBW and replace it with any other trinket with less cooldown (I dont like DBW mainly cos of the 105sec cooldown), I can say that this trinket is best for every class that has auto attack that does a majority of its damage.
From Fury Warriors, to Unholy DKs, to Enha Shamans, to Assassination Rogues, everyone wants DBW!

P.S. The only reason Ret paladin does not want DBW is because TaiaJ is made for the class, and STS is the only ArP trinket in the game that is better than DBW.

Use DBW and hope for those Strength (attack power) and Haste procs!
