How good is the vault speed build?

[achuso]

People seem to hype it a lot, but I just tried it for myself and couldn't notice much difference. Is it worth using at all?

For those who don't know, the build is as follows:

-Resilience
-Spine Chill
-(optional) SB, DH or Lithe
-(optional) Adrenaline, DS or Iron Will

gives you a lot of safe vaults which otherwise would be death, and killers often swing but you vault faster so they miss. also helps in bloodlust scenarios around a pallet and the 9% gen speed is nice. its pretty good if you know what youre doing

If the killer's ping is high enough, you'll get hit anyways. It only works on low latency where you wouldn't get hit through the window anyways. But that's from my experience.
I think I tested the vault speed combo in a KYF a long time ago and these 2 perks only added less than half a second to the vault speed. I don't know if it's a placebo effect or the people running the vault build were getting lucky with the killers who had decent internet but when I was using this build, I either was still getting hit through the window/pallet or the killer missed on a vault that I could already make without these 2 perks.

It's very good but requires two perk slots (resilience + Spine).
It's a lot, I dare say it's too much XD.
Fun to use from time to time though.
