I ran into this spot while questing pre-60. I guess you could do it post 60 but, it isn't as good as NV farming. I've gotten a couple of notable items, so depending on your luck, you could make anywhere from 100k-250k per hour.
1. Start the quest "The Broken Blade: Talk to Alaric."
2. Talk to Alaric and go across the bridge.
3. Get to Warrior's Rest.
4. Kill everything, do not get the quest item at the end. You're guaranteed a rare pack with a chance of two chests.
5. Re-Log and do it again.
6. Tons of Blues, fair amount of rares.
First post here, I searched but, couldn't find anything relevant. Sorry if it's a re-post.
As you can see, you also get Leah as a super cool assistant. She isn't very useful, and she doesn't do much... And she talks a lot... But she's there. Entire thing takes like 2 minutes.
Happy farming!
