Hi guys, are you all running Deathbringer and Flurry Axe? Is that the best combo? Seems odd that a low level epic is so prolific.
Get used to looking at the attributes on a weapon, rather than its ilvl in isolation. 
Deathbringer is indeed the BiS Phase 1 Main Hand weapon for dual wield. https://classic.wowhead.com/item=18832/brutality-blade From Garr in MC seems to be BiS off hand.
I got deathbringer on my first ony kill back in vanilla. Replaced it in Nagrand…
Don’t worry about what weapons are BiS. Try for them all and thank rnjesus for what you get.
