Yea but having all that stuff in game for permanent could cause a stack overflow, that much info just sitting there all that time so they would then have to have more space made.
You know what is really horrible? Earning the elite sets, got 2 for shammy EU and 1 pally EU, warrior on US realms I got and if you get some elite piece but not all of them when they are up for buy then you sometimes can never get the pieces you missed out on getting, they won’t even give it in a ticket even if you prove that you earnt them. And they look so unique that they almost never match with any other mog. I hate when I do not match in game. So yea I kinda think that elite sets should stay forever. Like just make more storage space if that’s what it takes but now I think they can keep all those extra sets without a worry. But have it still region locked for earning it.
