Say goodbye to the old weapon frames because they're going away on July 30! No more will you possibly get confused by the very faded border indicating which weapon belongs to each class because now they share the same style as normal cards! We haven't seen all the frames yet, but things are looking nice for Hunter!

Quote From Blizzard

With the introduction of Dual-Class cards, we went back and applied a class specific frame to every weapon in Hearthstone. Class specific weapon frames will appear in-game starting July 30.
