I have a serious and non sarcastic question:
Why does someone else having an item later affect your enjoyment of the item? You had it first, so you have your "unique" time for about a year. It's not as if someone else having it makes yours look or act differently.
I'm a huge proponent of everyone having access to everything, let people get the items they want or make progression towards those items at least. So I don't understand people who want to limit others access to things.
I did the whole yokai grind, got both mounts (it helped I was doing anima weapons at the same time) and I've also got the brickman and shantotto minions. I would LOVE for others to be able to get these things, especially if it would complete their collections or outfits.
I get wanting to limit them to events to make them feel sort of special, but some events never repeat and some people will never experience those events (I have a friend who always away during new years and never gets those items).
it sounds like you want to deny some people access to these items, and that sounds mean. This is why you're going to get pushback.
also, as has been said before, asking SE to out and out STOP something that's proven and working to bring in extra revenue is not going to happen.
