Seems like you are describing ping issues or lag.
That does not happen (unless maybe you have 2,000 ping). I play with 200 ping often and don't have any issues at all provided I exit the red circle before it disappears.Aoe Zones hitting you even though you were out before the circle was gone
It is true that the animation often begins after the red circle disappears or after the cast completes. It is true that many gamers are probably used to responding to animations rather than "cast bars" and may always die to everything as a result and feel the game is weird because of it.and the Animation even started.
But as long as you resolve a mechanic before the cast completes, that is how you solve most mechanics in this game, with a very small number of exceptions where there is an visual cast bar ahead of time before an uncasted one that actually snapshots it.
True, this can happen with invulns where you press them but die before they activate. But I do not blame a "tick rate" for this. I blame the animation delay, which I believe should be removed for abilities.Hitting a CD and it not going off, but GOING ON COOLDOWN (Looking at you Tank players)
Now, this part is true. Sometimes you can successfully cast on a target and the server accepts the cast without error, but no effect occurs because the target died. This can happen with a hunt target where you get 1 hit in and it was accepted by the server in the battle log, but it didn't result in any rewards because it died around the same time.Completing a cast or Heal only for it to vanish into the void because the target died.
In a similar way, you can often still run around for a while after a red circle hit you, but you know you are going to die in 2 seconds because you saw the red circle clip you. What seems to add to this is that I think movement is not something that is thoroughly verified as something you are able to do (probably to prevent rubberbanding), otherwise it would have to return you to the location you were at when the red circle hit you.
It has been posted before. There were even determined efforts to report part of it as a bug.if the the devs don't check this Forum
