Forum:Soling Crawmerax

Ok, so I solo Crawmerax quiet frequently, but I have run into a problem. 9/10 times that I solo him with my hunter, he just faces me and does a repeated growl, allowing me to snipe all of his body parts except the back. I hide in a non-glitched part of the map that allows me to be far enough away that he doesn't recognize me. I need help getting to his back without dying. (He puts me in last stand in one hit, and normally nothing is around for me to shoot tog et second wind.) How would I go about doing this. I have attempted shooting at him with my ndhoong, but it doesn't help really. Any suggestions
