It could work along the same lines and would be awesome when one is tired of wearing the same style for months but cant change one's beloves golded set ...
I've seen others post that it's coming - I do hope it is. And, I also hope that it's not locked behind only certain content. The re-trait system leaves solo questers out in the cold (though, arguably, they don't really have much need for retraiting, since crafted gear works just fine for that).
But, since it's changing appearance, I'm hopeful that it will be more accessible.
