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

I'm well aware of delay but i still get cases where i see other people clear of the radius and getting hit by it.

What kind of delay is going on when it has to communicate between them and the server and then communicate between the server and me to tell me where they are and the server says "they are clear" yet it still hits them?

This is most likely another of ARR's flaws on display: Animation Delay. If you've been primarily playing casters, you won't notice it much from the player perspective, but most "instant" attacks and abilities have a wind up that has to play out before the damage or effect is (visually) resolved on the client. A great horrible example of this is the Dragoon's "interrupt" ability that, according to a couple of DRG friends, takes about 1 full second to actually apply the interrupt due to animation delay.

This can and does apply to bosses, too, and then ends up making the already-terrible positioning delay look hilariously awful. Example: Boss casts AOE attack. Red circle appears on your teammate next to you. You both start moving, but you have a head start because the circle was centered on him, not you. You clear the red circle. Position check occurs. He clears the red circle on his screen. AOE cast completes, a "hit" is calculated on your teammate because this game is bad. Boss starts animating the attack. Position check occurs. You now see the teammate outside of where the AOE was. Boss animation completes and damage is applied. Teammate eats damage, dies, standing in what appears to be "safe" area.
