I (26 druid) also managed to solo her. I simply stealthed all the way into her, then while she was on her little patrol I killed her nearest add so I got some space, then I attacked once she got back around. It was a long and tough fight, but I won in the end. Unfortunately she dropped that stupid bow, just like mentioned above. Will kill her again tomorrow morning.
