However if you run down straight in the middle you can avoid most of them (the statues are lined up at the sides, like a big corridor).
Also it seems like the dungeon itself is now always open. But they waypoint isn't. Also of course mobs and hostiles lurk around if the entrance isn't conquered. I guess they opened it up after people stopped doing the events as much as they did initially after release. At least on my server neither temples nor Narthex get freed. At most one per day or so.
