I would like to see special rewards that can be found in-game only by completing special quests. Cool items (rewards) that can't just be bought with crowns.
I like the badge system because you can't purchase them, its through accomplishments only. It would be nice if there were other items but especially cool usable items like special clothing or wands.
Maybe this does happen and I'm just not yet aware. Wizard Cup in Wysteria is the only one I am aware of.
I find that anybody can purchase a cool outfit if they spend money, but hard working wizards should get something they can show off that you can't just buy with crowns or in the bazaar.
Examples might be: - completing a major quest. - doing a special side quest. - completing a specific quest with a wizard below a certain level. - rare and unusual accomplishments.
On a similar note, I have yet to "keep" a clothing item found or dropped in a quest (one exception - a hat i liked the appearance of). But generally stuff found on quests is inferior to anything you would purchase at the bazaar.
