Wardless Looper - give me your opinions and feedback

Ok so I made a build that I was thinking about for some time and I always hear about wardless build being much more pricey - well which it is :D but usually people say that it ends up being less tanky in the end but from my end it does not seem like it, atleast compared to some high investment wardloops I checked it seems quite alright. Here it is:

I think u can build this much cheaper, without voices, sublime vision, corrupted uniques and some alt gems, I think you could assemble something that works within 50div.

Can you guys check the build and propose upgrades or if you find about any holes in the build let me know. The only thing I am thinking that could brick this is not enough mana for skeletons loop if I ever get hit that would completely deplete my mana in 1 server tick so it would need to be around 4k hit after all mitigation. If my mana wont go down within 1 server tick I should be fine no? Well my mana is not completely 40% of my life but if this ever happens I would most likely die anyway, but does anyone know how it works with this automated triggering? :D I guess the hit would need to hit me exactly at the trigger server tick or maybe the one before?

Anyway I am taking 3840 damage from my loops, x5 times a second x4sec (recent for recoup) so thats 76800 active recoup from just my loop. Then I can divide it by my recoup which lasts 3s and multiply it by 1 server tick is 0.033 s
97% recoup - 74,496 life / 3000 * 33 = 819.456 life every server tick
52% recoup - 39,936 mana / 3000 * 33 = 439.296 mana every server tick

correct me if I am wrong

Anyway what do you think about this build? also any suggestions on how to improve phys hit? And is there any hard hitting chaos damage that could kill me??
