Well, to begin with, I was thinking of making 2 new tournaments, which would be MONTHLY and not weekly as the others are, and the rewards from these monthly tournaments would be backgrounds (pictures behind our heroes) that would have the place of the player (f.e. Champion for 1st place, top 10 for the rest 9 ranks and top 100 for the rest 90 ranks), as well as the month and the year of which each hero achieved that rank (f.e. ''January 2014'' but although the tournament was held in January, it is obviously that the rewards will be awarded at 1st day of February).
And here are the rules of the 2 tournaments I was talking about:
1st tournament:
-the number of duels each player won in a month
2nd tournament
-the number of missions each player completed in a month
Although it would be nice to also win a prize like donuts or skill points in addition to the backgrounds
