NIN LB Snapshot is Problematic

So as far as I can tell, NIN LB now works like this with the new snapshot:

1) You hit NIN LB button on target
2) At that moment, if the target is below 50%, they will die (later on when animation actually finishes, though)
3) NIN LB animation goes off, target can still guard, heal, move, etc
4) NIN LB animation finishes, target dies

I'm not sure what the purpose of the new snapshotting giving people time to react if reacting doesn't do anything in the end? Either revert it back to the old way so you just are locked out of moving/actions ASAP, or allow our healing in the NIN LB animation window in order to have a chance to avoid the instant death.

NIN's LB is notoriously awful on both sides of it, even in 7.1
As a NIN, it's incredibly frustrating when you LB a target at 20% HP yet by the time you hop on their back they've healed are are good to go. I've had instances when the damage rolls out when their hp% is still under 50 only for the server tick to catch up and the assassination fails. On the other end, I've been NIN LB'd and reactively healed and still died, but the former seems to happen much more often than the latter. The NIN Backpack-of-shame is much more common than an unfair death.

What's worse is that 9/10, I'm still hit by some ranged attack 2 seconds after going invisible through Shukuchi. I'm baffled that they didn't adjust the timing on that, it's truly awful.

XIV netcode paired with terrible delay decisions, gotta love it!

You both are sending mixed signals, is Seiton affected by the hit resolution changes or not? Before it was based on snapshot when the skill was used, even if the target regained HP before the animation.
