Safety is a myth
There were 5 of us and we entered a dungeon, a hard tough one. Before you entered there was an option to modify one of the mob types, and a T-Rex type mob was chosen, and it was given long flexible arms and grasping claws, as if this dungeon wasn't hard enough already. That turned out to be a mistake as we were perpetually fleeing from these T-Rex creatures, nowhere we could find was safe from them :( We had lost them at one point, and came upon a boss we thought we could handle, who dropped good loot so we went for it. As part of that I closed a nearby gate to stop any adds from joining the fight, but there was a duplicate boss hidden there and that joined the fight as well. 2 bosses was too much for us and we fled with 2 people dead :( The bosses stuffed one of our team mate's corpses and used that to lure the T-Rex's after us and our fleeing began again :(
