Well, I never really soloed much as a Hunter, besides being proud of soloing Devilsaurs at level 52 with a level 51 pet.
What I do remember soloing though, with my Druid, is Mother Smolderweb. I really wanted the Wildheart set. (This was a long time ago) And I knew Mother Smolderweb dropped my last set piece. So I decided to stealthrun the old lass. Only, I couldn't get any Rogues or other Druids to help me.
So I decided to see if that little myth I had heard was true. I stocked up on Mana/Health Pots, some Tubers, and a few buffpots and scrolls. It turned out I wouldn't even need those.
It was almost like exploiting a bug. Just use Starfall, and immediately Hibernate on her. Wait until the Hibernate has almost gone through, and another Starfall. Switch positions depending on how close she gets. Rince and repeat, use a Mana Potion when necessary, and after a LOOOONG time doing this, she died. Switch to bearform, run in and loot, and most likely die from the tiny little sons and daughters she spawned.
The Boots didn't drop until the fourth time I did this, but since getting groups there was pretty much a no-chance-in-hell situation, it was worth it. Funny as hell to, when people asked me how I did it, and I just said Stealthrun and Bearform the lass. Until they realized how much of a lying little ***** I was, I was considered almost a god amongst the Druids in the guild. I made up for it by paying their repairbills though, hehe.
