This dungeon is suppose to be ran at level 35 with, 5 – 35’s not 5 -80’s. I do believe you have made this dungeon a bit hard. The spider on the first round, all of those hatch-lings can take out 4 level 80’s, so running it at level 35 which it is suppose to be ran at, is almost mere impossible. GW2 will have to nerf this soon.
