Best class to farm with using 100M in gear?

I currently play a DH and have been farming just fine. I don't even mind the nerfs and still farm ok, but the DH playstyle just isn't "fun" (I didn't originally roll one but gave in to farm gear for another class) to me.

Well now I have 100M gold and it seems that some other classes may have caught up or passed DH farming potential. If you had 100M gold to buy gear, what class would you want to be? Melee Wizard? Monk?

Curious to hear what and why!
