But it makes it much harder to do things that require a lot of people like fame trains or lost halls
take the bulwark reskin for example, it way fairly easy to get, however getting a normal bulwark is a lot less special when you could get one just by doing ~50 ice tombs
Thus there will be way less people farming a dungeon/event if the reward can be obtained with way less work through a dungeon chest like it was the case with the freezing quiver or the nest uts.
