After watching some of the media tour interviews with YoshiP it became clear the devs aren't quite aware of how certain jobs play at high ping.
So here's a video of me trying to weave certain skills during Machinst's Hypercharge window.

details for the devs:
I play on PS4
I have a WiFi connection, not a direct ethernet cable
I get roughly 180ms to Aether from Australia (on a laptop, I'm not sure if console plays a role in this)
My ISP is Telstra
It has rained recently (that sounds like a joke but apparently that matters here)

Jobs with tight timed windows like Machinst and Dark Knight are very difficult for me to play at this ping. I don't think I've ever seen a proper 5/5 GCD Blood Weapon window and it's basically hit or miss if I ever see 5/5 Fell Cleaves. Jobs like Gunbreaker that ask you to get [x] amount of GCDs under a buff like No Mercy aren't really something I can comfortably play in content that requires higher DPS output.
With conditions like these it does impact my enjoyment of a job and how likely I am to play it. I don't bother with Machinst outside of PvP content nowadays.

And before people comment: yes, I am excited for the new OCE servers but no, I will not be moving my main character there. I've played on Aether for over 5 years now, I have friends and connections here that I don't want to give up on just for ~20ms.
