Stolen from Geocaching.com. We could have calendars added to each profile. Every time you battle on a date that date is crossed off. The goal being to cross of as many days as possible and complete your 365 day calendar. This works well with Geocaching as people do make deliberate attempts to fill the calendar, I see no reason why this couldn't work with Letsbeef.
People would need to battle 365 times at a bare minimum to fill the calendar, that's a ton of activity!
Obviously this would require adding by an admin. It could be a fresh addition to profiles or could replace the redundant skill ratings. Thoughts?
Here's an image of the Geocaching.com system. The numbers reflect how many caches have been found on each date:
