You need to make this go mainstream to maximize its value. Therefore please remove the little commendation tab at the bottom right of the screen at the end of the dungeon and then:
1. When you exit a dungeon the screen changes to the new commendation screen displaying adventurer plates
2. You click on the one you want to commend or a No Thanks/Skip
3. You load into the overworld
Then, people will actively be very interested in making their plates as cool as possible.
Late Edit, this is more or less what I mean, taken directly from the PVP page and modified with Paint a bit.
