Yes, I have tried to tell you and your ilk this sever times in past threads, but for some odd reason, you continue to, y’know, not get it. Legion artifacts, for example, retired, but were replaced by Azerite traits. Gems from the prior expansions make way for new ones made with new mats, and so on.
You keep trying to sell us this Chicken Little story about Mount Equipment being retired with no replacement or similar system; this is your personal doom & gloom scenario that makes you look foolish everytime you spout it.
