I remember first week of the server in light of exploring the world, partially dungeon.
Dungeon was great challenge, we were up to 12 people levels 9-12, did not know to expect, died in there more 10 times each time losing full set of gear... Second week dungeon was nerfed, we gathered 6 better equipped people and finally got to the exit. Though boss with broken camera managed to kick us all 5 more times. We found right tactics and finally done it.
It was the best quest / dungeon / challenge in all PvE part of Fonlines ever. Sadly, dungeon get nerfed even more later.
Right now 3 people can finish it easily, not really relying on any specific tactics and discipline. And that's sad.
