Guild Wars 2

Location : Raid Wing (3) Keep Construct door entrance.
Boss : Keep Construct
What Happened : All players (except the first that got though) died at door entrance instantly upon entering.

Please investigate unto this.
Thank you.

To clarify: Keep Construct aggros immediately when anyone crosses into the doorway to his room. There seems to be about a 2 second window between the first person entering the doorway and the doors closing, and the distance to cross to avoid being instantly killed by the doors is quite wide (approximately the visual model of the open doors).

Even when tightly grouped and running in together it’s necessary to use swiftness and movement abilities to avoid players being instantly killed on entry.

edit: in addition to the door boss, the named ghosts in the encounter slide all over instead of walking toward their fixate target- cue Jamiroquai “Virtual Insanity” music video.
