WoWProgress has implemented a new feature to spice up competition between guilds. Next to the zone and realm rankings you can now see the fastest kills for every encounter. This way you can compare a specific guild with others and see who's currently the fastest and how much gear has improved the kill times each week. They track the time, setup and itemlevel of the group. To not mess up the data you should not change more than two members of your group.
They are also planning on adding specific rankings for regions, zones and realms for a better overview.

Once the realm rankings are up this might really boost the "local" competition, as guilds pick the best setups and strats for the quickest kills to be the No.1 on their respective servers!
