1). It happened 2 times. We don't need it.

2). All the people gthat put the work into it for the "limited time item", it would be unfair to them(the ones who care) to just give it out again.

I personally don't have it. I was just starting arr the week it was ending.
But if I did and had an item that was rare and limited, I wouldn't want it just given out again. Would ruin the special feeling of having something that not everyone could have.
