solo'd as a 40 feral druid. To start, just spam starfire and moonfire (when the dot expires), keeping a safe distance by rooting when necessary. when OOM, use a mana pot, then use innervate and continue rooting/starfire/moonfire. When approaching OOM the 2nd time, go to bear form and tank him a bit. when you get to 1/2 hp, activate nature's grasp and when the root procs get out, pop a HT and rejuv, and get back into bear form. You might have to do this a 2nd time when NG's 45s CD refreshes, but after that he should be under 10% and your pot CD should have refreshed as well. Hope this helps!
