Although, I am in total Sympathy with those doing the bugged quest where you have to wait for the gargoyle to attack the NPC in the graveyard, but players natural attack him, breaking the quest.

Shame on you ESO for not fixing this poor design!
However, for the 50+ poor souls on the deck who are pleading with other players not to go into the Graveyard or kill the gargoyle.....don't waste your time getting your blood pressure up.

Here is why- if any player dies in that town, and they select "respawn at the nearest wayshrine", the game respawns them in the GRAVEYARD and NOT a WAYSHRINE.
Talk about a bug.......the graveyard is not even a wayshrine!

With this kind of poor design and bug, no matter how much you plead with other players, all it takes is for one of them to die elsewhere in town and they will respawnin graveyard breaking the quest again, thru no fault of their own.

Also, many players doing the quest for the first time do not even know its broken and go to the quest waypoint just like any other quest way point, not realizing they will ruin the quest.

Thus, do not waste your time...other than trying the quest off peak hours when their is a low pop of players.

Until then we can only hope ESO fixes this soon as well as all the other issues.
