Want feedback on this build

https://pastebin.com/mpgA67BJ. Is this viable for the end game? I'm currently just at the start of mapping, I think I have reached T4 and fought Baran once, but I want to respec this character into the build above, because I started to die way too often to my liking, so I adopted as much defensive layers I figured I can realistically do while still doing enough damage not to get stuck on each magic monster pack.

This character currently runs pretty much all the same build, but with a different tree and different utility gem setups because initially I had a different build in mind before finding The Three Dragons and deciding to give it a try. I liked the play style and want to commit to it. The gear in the build stays mostly the same, although I corrupted some pieces for future reference. When I'll gain currency I'm gonna find better pieces, especially for the currently absent chaos resistance.

I'm not sure if the decision to go for Phase Acrobatics is optimal, costing me quite a bit of skill points, maybe I'm overlooking cheaper defensive options.

At some point I probably will drop the Snakepit in favor of a different more suitable ring once I find clear to be adequate, especially during Legion, Incursion, Heist or other timed encounters.
