Why do casual players seem entitled to cosmetic items added in game?

By your logic, as soon as a clothing company adds a new shirt to their collection, the next day everyone will want to be wearing the same thing.

By my logic, if something simply were added to the base available options, it becomes just another option in a pool of them, and it will have its place in the distribution of which hairstyle people may pick for their character.

By your logic again, every character should come out of character creation looking the same, because one of those options in there logically has to be the latest to have been added.

The only time I have seen a phenomenon where suddenly almost everyone was using the same clothing or cosmetic items, was when the Nier raid dropped 2B gear and whenever a seasonal event awards an outfit that fits in with the event theme, and even those times were always quickly passing fads.

Yes, and the Nier raid reward dropped every time and was casual content. It would not have been nearly as prolific if it was a savage reward. Hence, it would be more unique. Thank you for providing a great example of my point.
