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!
