I'm getting ready to build my Infernal Machines, and I'm trying to decide if I should start looking for groups to run with, or if I can handle the fights solo.

Given how time-intesive it is to obtain sufficient keys to build a sufficient number of Infernal Machines, I'd like to complete the Uber boss fights on a higher MP level.

It seems like most of the strategies I see assume you are in a group, so you can split the bosses. Is that required, or are other tactics for a solo player viable?

I can comfortably farm MP4 with my MF gear, and could probably handle MP6 or even higher. Is it realistic to expect to be able to solo farm Uber bosses at, or slightly below, the MP level I am comfortable farming?

If class is a determining factor, I play a Witch Doctor.
