Not only it is classified as a 69-78 level dungeon, but the enemies there are grey to you, giving you no XP per kill and hindering it for the rest of the group due to the anti-boosting system they implemented a while ago to discourage high levels to blast through dungeons to level other characters
You basically have to eat the deserter debuff to not waste the time of you and the people in your group, and it may have happened to me thrice already. It would be nice if they retouched the dungeons available depending on the level range so this situation doesn’t happen to other people in the future
