I noticed a very interesting edit they made to the Alternative Tier sets post, which has pretty significant implications for a lot of players. Please see the attached pictures below:
Updated post regarding the swappable pieces

Previous unedited post (5/21/24)

Now, I get it, things are subject to change. When it comes to most things, I understand. However, this has significant implications for a lot of players. People have spent their time and gold getting these tier pieces in anticipation for being able to trade them in under the pretense that they will be able to trade them in. For some classes like rogues and warriors, it's pretty easy to get extra tier pieces. However, there are other classes that require significant amount of time and gold to get their respective pieces (Shamans come to mind).
I'm not personally effected by this, but many players will be. There is no logical reason to make this change other than to punish people for preparing for the upcoming patch, which you provided incomplete or false information on.
You need to fix this.
