[3.0] flicker strike oro's sacrifice (needs help!)

Hey, admin please move if this is the wrong section
this build is working fine though i do have some survivability issues

for those who have "path of building" installed, here's the code for my build

and ofcourse, the rest of the info

look for SIGHILDE:

end result is "workable" damage but only 3k life!
i'm wondering if any build gurus out there can assist me in min/maxing this as i find simply "follow this build someone else did" kills the fun for me, but as far as i can see it's either i boost damage or health at this point and i would like both

ideally i could do with GGG RRR on my bronn lithe's to accommodate increased ele damage support gem but that doesn't help my life situation!

a friend of mine says it's because i have nearly no "+ to maximum life" on any gear but changing those would negate ele resistance or damage - thus dropping survivability too

any advice/ideas?
this is my second attempt at getting back in the game after my previous main character (ranger) was brutally nerf'd but i'm hitting some kind of limitation somewhere along the line

but let's not talk about what happened to CoC... :( RIP.

Think about an Eye of Innocence Unique Citrine Amulet, get +Maximum life jewels for the almost connected tree sockets, you can also get more damage with those.

On the Top of the Tree you went for the "Heart of the Flame" notable, the "Breath of Flames" next to it is also interesting for Oro's, due to the ignite chance
