INFECTED CHALLENGE ALL WORLD LEADER BOARD!!!!!!!!!!!!!!

CAN there PLEASE BE AN  ALL WORLD LEADER BOARD for the infected challenges !!!!!!! the overall kill count at the top of the screen is an all world included count,  so can there be a top player leader board  added during or shown after each challenge completion.  also a cool  looking BADGE be sweet for 1st 2nd 3rd ranked all world players  . not ONLY a challenge metal . i know THE challenges are just about ALL that brings my old worlds to life and the added achievements could really gather all players from the game as a whole some where similar to at the least compare. at the MOST see players  some where they had not thought to be playing still . I COULD GO ON  , the leader board can link to the forum for commenting. increasing traffic here.
