I would like to see a return of the plate type armors in D3. The Assassin looks so cool in gothic plate. Many of us dislike the "flaps and straps" approach. I feel that both visual types could make it into the game and please more people.
These armors would look hella cool in the new 3d engine. acid etched plate armor...woot!
When fighting hell spawned demons thicker heavier armor just makes sense to me in the diablo series world.
