Here is a note from EA concerning some planned crackdown on people being naughty that was sent out to ranked server admins.

We have noticed an increase in behavior where leased servers are being used by clans solely to pad players stats, even to the extent where clans are institutionalizing rules that forbid normal play. Currently the favored method is for player admins to set rules where players must use either a knife or Pistol, players must revive each other, and players must not take flags. This creates environments where players gain stats unrealistically and creates an imbalance in the ranked server playing field. In our opinion, these players are breaking EA's Terms of Service, and we have begun taking action on the clans involved. However, clan coordination to this extreme requires us to create a long-term solution for this (separate from any scoring changes in 1.03).

In general, I've enjoyed the entire rewards/badges system in Battlefield 2. Having those cute little awards pop up every so often telling you how super awesome you are is really fun. I mean everyone knows on the inside that they are awesome, but it's nice to have some validation in your life by a computer program.
