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

[reality_check]

The second one, is normal, you hesitated there for a second and that got you in the end. I know, the timing is a bitch, you have to move the instant the plumes appear and not stop.

There was a slight hesitation in his movement; however, it does show how out of sync the game is. He could have reacted faster but there is absolutely no reason why his death should happen SO far away from the AoE. If you get hit by AoE you should die in the AoE. Not after running 10 yalms and then the client being told you got hit.
