The point of this thread imo is that if you move out of the red it shouldn't matter when you did it. If you are out of the attack you should not get hit, even if it was the last 50 milliseconds. THat's where people are complaining about the way it's designed and how latency affects it. I'm not saying I can't do this or that, just that the latency issue exists where you get it by it even though you are clearly not in it, I saw it on chimera, I saw it on hydra, I see it in AK on the first/second/third boss, I've seen it in every piece of content I've done.
So like others have stated I just move before it even happens my predicting it, which isn't always possible as some fights randomly cast stuff.
