There is no kiting elite packs in MP10, as these elites and minions in total have hundreds of millions of health, and may also have teleport built in, as well as teleport, There is no killing mobs while smoke screened or spirit walked.

And of course, you may just zone into a dungeon to face a triple CC elite pack (or in this case a triple CC pack between the two sets of elites at zone entrance, with their couple hundred million total health.
There are multiple ways to survive this. 1.5M EHP is one option, which may be reduced with gear that ultimately functions as CC reduction to around 1M. CC break skills are another, if they are relatively free to use and spammable. Pets take hits, and reduce the number to around 1M. Alternatively, delayed damage skills or damage over time skills combined with LoH and LS may also reduce the number to around 1M. Or you could be a barb and spec for CC immunity or heals on CC. Dodge isn't included in this EHP, as the highest burst involves CC + lasers/desecrate/molten, which cannot be dodged.
Surviving the damage is actually relatively cheap and straight forward. It will happen, you just math out what gear/spec you need to deal with it.
The second challenge are the hard enrage timers on bosses. SK, Belial, and Rakanoth have hard enrages that basically 1-2 shot you. Rakanoth on MP10 has around 100M health and deals 1-1.5M EHP dps to you past 3 minutes. You have to deal 540k dps in total to avoid mp10 2 shot enrages. But Rakanoth also teleports around, knockbacks, and summons adds that knockback, so you generally want a setup that deals 600k dps to him as a barb, or 660k dps as other classes.
This is generally the expensive part. In order to output 600k dps, you generally need 100-150k character dps. What makes this expensive, is that you still have to keep the 1M EHP buffer at the same time against CC burst, unless you are a barb using CC immunity. However, because of this, many have or are switching to barb, inflating the cost of barb gear. For example, the 1.05 IK set is currently more expensive than all four other 1.05 sets put together. A Str Mempo is 20M, 2.5x the cost of a dex mempo used by twice as many classes.
What makes this especially expensive, is that it prohibits use of a shield, as I have yet to see a 125k dps shield user w/ 1M EHP.
Double shrine Rak at 75k dps illustrates what happens when you are at less than 660k dps:
The third challenge is healing back up between 1+M EHP bursts. However, at the all resist and armor necessary to get 1M EHP without dodge, and DPS necessary to deal 600-660k dps, lifesteal and delayed damage skills generally fits all requirements and will heal you through reflect and CC. Yes, you will generally need high lifesteal on your weapon(s) and at least one skill or passive as well. I would avoid LoH entirely regardless of proc ratios, as future proc ratios are unknown and change significantly each patch, and it takes a long time to gear up for MP10.
So ultimately, to survive mp10 you are generally looking for 1M EHP, the dps and spec necessary to deal 6-700k+ dps with delayed damage skills that work with lifesteal, and high lifesteal. Or you can be a barb with CC immunity. Or both, which is what I am working on.
EDIT: I was wrong, in order to kill mp10 Belial, you need 1.2M dps. Combined with the EHP requirement above, there simply aren't enough affixes available. Therefore, the only way to survive in MP10 (all of it) is to be a barb.
