with a little help from my friends

I will admit it unashamedly: when it comes to Diablo3, I am a total Noob. But I am learning, little by little. I know now how to defeat Maghda and Azmodan manually. But what I still do not understand, is whether it can be done botwise. I left my computer for a few hours unattended, and when I came back, it had been still trying to kill Maghda! It was in expert mode, and I must admit that while I had done it manually and without any difficulty in Normal and Hard, I just could not kill the bitch in Expert mode. And, like I said, neither could the bot. I was playing a DH, and while I looked at the fruitless attempts of the bot I realized that my toon died each time because it let itself get surrounded. And that happened because Fan of Knives is part of the rotation. A very powerful spell no doubt, but a suicidal one when it comes to the Maghda and Azmodan episodes. So I suppose I have at least 2 questions for our advanced brethren:

1) how can I change the rotation and eliminate Fan of Knived when needed?

2) Did anybody's bot succeed in killing Maghda and/or Azmodan unaided?

Any other tips or suggestions will be greatly appreciated.
