As far as I know Blizzard considered this but backed down when a bunch of people threw a fit about it.
But I don’t understand why.
The only argument I’ve heard is that classes play differently every season so having that armor proves you did well as that class. But if what those people want is a little trophy to prove they did good as a class that was slightly low tier one season… THERE’S ALREADY A MOUNT AND TITLE FOR THAT! What more do you need?!
And do you know what’s also affected by class balance every patch? PvE! Yet PvErs can get Mythic gear from any patch whenever they want, even when the raid becomes soloable. So how is that fair? Should we take away Mythic appearance from players who didn’t get AOTC? At least it’d be fair then.
Although is people insist on blocking old armor behind a wall can’t we at least give players a token that lets them buy old Elite sets like we do for the Vicious War mounts?
