I think it would be pretty awesome if a profile of the guild (where you can see the guild hours) have a total list of the members stats. For example

Guild total for Player killing: 6,900,000
Guild total for Sparring: W: 250,000 L: 30,000
Guild total for Baddy killing: 5,009,000

There can also be high scores for the totals. Up to the devs
