1. Go to BRD by yourself as a lvl 70.
2. Use the mole machine to the right to get to the brewfest boss.
3. Kill all the yellow drinking buddies by yourself... and loot for good stuff. Each pull of about 10 to 20 has one lvl 49 elite in it, the rest are non elite.
4. Go out and reset BRD.
5. Rinse and repeat.
I've looted lots of blue and green profession recipes this way that sell on the AH for up to 100g a piece, if not more. Plus you get some coinage and other grays that sell for about 10+g per run.
I do it as a mage, so I just AOE them down. Takes about 10 mins per run. If your bags get full with gray junk, just sell it to the arena vendor right inside that room.
If you get a healer you could probably attempt to two-man the fire boss down the hall and get some more loot.
Hope you find it useful.:wave:
