I would like to address the following issue. Have you recently joined a bg, and most of the players on your team are from Blackrock. If so you have also noticed more than 90% of them are just AFK. The step one would take is to report them. Okay, you have them for a few more minutes, and they are kicked out of the bg. Who comes in your team now? Maybe if you're lucky it will be someone who is actually playing. However, a lot of the new players are again AFKers from Blackrock.
Please remove the cross-realm on Blackrock. Even if the wait time for BGs increases, at least you will actually play with people, and not just AFK bots...
