Appreciate some feedback on my build

What do you guys think about this build theory of mine? https://pobb.in/JtpeQfs28LvA

The main goal and idea with this build is to be relatively easy to build and acquire even in solo self found.

To summarize:

• Hybrid life and energy shield
• Utilizing both new chaos damage mitigation masteries that will be available with 3.21
• 55% Low Life with petrified blood
• Inquisitor
• Really good sustainability and regen
• Good damage mitigation and effective hit pool
• Cremation in Sire of Shards (36 projectiles per second, or 48 with lab enchant)

Some additional experimental thoughts/potential possibilities:

• Using Ngamahu's Sign in combination with the new fire mastery node "50% chance to refresh ignite duration on critical strike" which could be potentially be insane if that counts as igniting.
• Depending on what end game gear is obtained I think it should be relatively easy to get some additional base spell crit to reach close to crit cap, as well as power charge generation so that PCoC can be swapped out to some other support gem.

Some potential issues/problems with the build:

• What do I do in regards to being stunned?
• Will it be too difficult capping chaos resistance you think?
