Sorry SE, but endgame won't work if you don't fix something.

I'm pretty sure SE doesn't consider this an issue because you don't just accidentally setup your game architecture the way FF14 does. The game's lag is very deliberate and not something that's the result of cheap hardware, but rather something fundamentally built into the game itself.

So what we are saying is that it's intentional to get hit with aoe although you have moved way out of the marked area in line with the visual indication, and that you can also avoid this by running out then back in? This may be deliberate, but it seems to be the same as deliberately setting vehicle parking sensors to the wrong range:
Bang! - don't complain that you've just reversed into another car when you where getting a signal that there was plenty of room, it's a deliberate feature.

If they are going to stick with the built in delay then just adjust the visual timings to correct these. At the moment they are incorrect, a flaw in the game mechanics.
