Best trinket EVER!!!!!!

How Deathbringer’s Will Works for Hunters:

You get one of only three procs:

1. 600 (700 Heroic) Agility
2. 600 (700 Heroic) Critical Chance
3. 1,200 (1,400 Heroic) Attack Power

It has a 105 sec internal cooldown, with a 30% proc chance, lasts for 30 seconds.
That means that you’ll see about a 28% uptime (as opposed to 33% uptime with Death’s Verdict / Greatness).

Do We Want It?

In a word, yes. It’s a great trinket, and it’s fantastic for hunters. Unfortunately, most other physical dps classes will want it to. Different classes get different procs; however, the good news is that the procs aren’t as good for all the classes.
For the record, here’s the breakdown as we know it:

• Death Knight: Str, Haste, Crit
• Druid: Str, Agil, Crit
• Paladin: Str, Haste, Crit
• Rogue: Agil, Haste, AP
• Shaman: Agil, Haste, AP
• Warrior:  Str, Crit, Haste
