During certain synchronization issues with game myself and people I play with are dying to mechanics even when properly avoiding them. This has increased lately to the point where on several occasions the entire team has witnessed a player avoid a one shot mechanic and still get killed by it. Other times the player will move client side but to everyone else they are standing still. I have found that when this happens to me I have to relog and when I come back my character model is in an entirely different spot from where i logged out.
Many times i have observed a player standing still but you can here them in an entirely different area in content where proximity audio is active.
In raids this causes mechanics to be unable to complete. Relogging seems to be the only fix. This has the potential to happen numerous time during all content. The most I’ve seen is up to 15 times within a 30 minute period on one person alone.
