If you position it properly, he will kill all the adds as he spins around. Very easy fight.
I do the same thing. I would only comment that when he picks a direction he will ascend one staircase and after he comes back around descend the other. When he descends, you should be standing at the bottom of the staircase that he ascended. If you move too far up or too close to the wall he will pick you up anyway so be cautious. This is really the only part of the fight that you can fail.
