Enemy Scaling Clarification
I believe dead players count towards the scaling as well. If they didn’t, then having 15 people dead out of 20 fighting a boss would still make it a doable fight. Which it doesn’t.

Arenanet staffers have posted elsewhere on this forum that once players become inactive, they no longer contribute to the scaling of an event. That said, they did not share how long a player has to be inactive/defeated/AFK in order to stop contributing. It might take a few minutes, which in the case of a Vinewrath boss is entirely too long.
