I managed to solo it today on my lvl 20 Hunter Twink.
I knew from experience that mail users aren't very good tanks, so I brought a scalehide pet (for tankiness + 10% leech).
Tried first as Marksman, but realized that although I could basically delete each individual mob, I was drawing aggro and getting rekt by the large packs. Still managed to reach the first boss and proceeded to die to him.
Then I tried as BM. As long as you're against only 1 target, you'll never draw aggro, and if you properly use your resources (Freezing Trap, Feign Death, Turtle Aspect, Exhilaration), you can survive.
The only issue with it was that each run takes quite a long time. And with the 11% chance of dropping that juicy pair of gloves, I think it is better to come back with a friend.
