The customer service is fine, the infrastructure is fine, you don't know what you're talking about.
Example: if dodge the red circle and get hit out of the circle 5 feet away? really that was fixed 4 years ago.
And it's not broken here either.

YOu need to leave the AoE area by the time the casting bar finishes. Every time I do this, I don't get hit. This is when the animation begins. If you're complaining that you're out when you see the animation on your body, you were not out of the area in time. It is YOU who is failing, not the game. Beyond that, if you really are out before the casting bar finishes, then you are lagging and it is your problem, not SE's.

Titan's weights, ifrit's plumes and cracks, the instant I step off of these, I'm safe. Some of the animations on other AoEs are a bit delayed, but if you go by the casting bar you will always be safe if you got out of the cone/circle before it finishes. This is not an infrastructure problem.
