Few players have asked and suggested this.
When maps change to give reward exp and gold to best team. The team that had most kills on that map gets most exp and gold. But I would reward all teams (with less amount offcoruse) so that everyone is encouraged to stay more on server.
Geno said that this might be added in version 2 but since we are droping players we need all help we can to bring players to play.
So just an idea.
