The Knights of Lordaeron have recently started doing some 10man rated BGs. We seem to lack people for a regular 15man premade and we could use people outisde the guild. PM me either on this forum or KoL's if interested or mail me in game.
Also, it would be fun and useful practice to arrange battles with the "War-game" option for BGs. If you have a 10man team and would like to try this new feature out with us, contact me in the ways mentioned above.
Good hunting and good luck!
