Duel Medallions and Seasons

Idea: make the Duel Medals for each season (Spring'11, Summer'11, Fall'11,Winter'11-12, Spring'12, etc.)
So, players could have Silver Duel Medal Spring'11, Platinum Duel Medal Summer'11, nothing for Fall'11, Bronze Duel Medal Winter'11-12. This way players could give more attention to mini-game "Duel".
