They need to use some AI upscaling tech to improve the really old low-res armors in the game, including the skimpy ones, and also need to add more.
We get maybe 1 set per tier showing any amount of skin. Last season it was Warlock and DH, this season it’s Monk (barely). DK hasn’t had a set showing more than an elbow since ICC. Warrior since Firelands. Paladin since Dragon Soul.
Literally over a decade.
