Just throwing this out there..
Grim Batol gets me about 300 to 400 gold per run without auctioning anything.
100% vendor.
However, if you do decide to auction, the valuables are:
BoE Greens/Blues and -about- 4 stacks of Embersilk Cloth per run.
Embersilk Cloth goes 80g per stack on my server. So that's an addition of 320gold to the profit.
If there's not a market for the weapons and armor, they can easily be disenchanted for materials.
I've not ran any numbers on that yet...
The run itself can take as long as about.. 14 minutes.
The boss is downed at 11 minutes for me - plus about 3 minutes to run back to the beginning.
So there's no risk of overloading the instance assuming you aren't a DPS god who pulls the entire instance.
However, with Honorbuddy's combat standards, I don't see that happening. Teehee..
If you can manage level 90 farmers, it's a great farm.
I'm looking into making an optimized farm profile of the instance soon.
