One thing that’s bothered me are the horned helmets from dragon bash, and the molten gauntlets.
For dragon bash, we got one helmet of each armor type. They all look the same
The molten ticket summons a vendor to chose what type. They all look the same.
The achievement armor used to have it’s preview set to heavy until you put it in your inventory. That bug has been fixed from the looks of it.
However, I suggest that a none armor type be created that can be worn by all classes to remove all this juggling and summoning of vendors to pick between identical armors, or preview bugs.
