The issue with PvP-Elite-Sets is that few know their recolor (and actually, the Myth+ recolors where almost always better^^) #Priskah #Transmogpic.twitter.com/rHumuhzMdr

I really hate that they remove the elite pvp sets from the game that are recolors of the Mythic raid gear. Just creating artificial scarcity to make very few people feel special.
A lot of top tier pvp players would not try every season if they would not get that feeling :D
