I just gotta wonder where you find bad players like these. I mean, its painfully obvious that standing in the red is bad and in ARR content some of the AoEs give ample time to dodge. Maybe horrible lag? Trying to connect to the server when its half way across the planet?
I guess this was more on Chimera and if I remember correctly it doesn't have much of the red aoe markers. Yes it tells you on the screen the very first time that it's eye changed colour after that you have to watch the chat log or watch the mob. If the new player is waiting for the next message to pop up on screen then yes there will be a problem.
