My pain attunement fire witch build! Opinions needed!

Hey everyone NerdRage15 here. This is my build for a fire witch that uses pain attunement. The goal behind this build is to use a blood magic gem linked to a aura so that I will be always be low on life granting me 30% extra damage. Defenses in this build include high resistances from the shield passives close to the templar start and a lot of energy shield (hopefully.)
I haven't started playing this build yet. I'd like to get some feedback from everyone to see what I could change! Link is below to skill tree :)

I see some missed out opportunities such as the 40% mana regen and elemental damage at start of templar tree. to much health nodes imo....you don't need much since you need to be below 30% and 2 auras with blood magic will get you there (discipline for shield @ some elemental damage aura), grab clarity without blood magic. you need more energy shield nodes for a pain attunement build. you will see that mana regen will be a problem for you so make sure to grab a bit more mana regen nodes or some other form of mana gain. Lastly the elemetal weapon damage....not sure its any use to you...wand and shield remember. anyways you probably already seen this vid but check it out if you didn't.

Just my 2c... I tried Pain Attunement, but with low hp I got a light radius of maybe 3 meters. I couldn't really see anything at all in dungeons etc; everyone was simply pitch black, so I ditched the skill.

the reason you had trouble with seeing with pain attunement is because you calculated your health wrong and went much lower then 30% health. whats most important is to sit comfortably at about 25% so that you don't get the screen going dark on you.

Thanks for the feedback fearlessness, I agree with what you've said and have altered the build.

This better? Don't know if I should go for crit chance as well?
Thoughts?
