Something along these lines would be nice, battlegrounds are miserable for the average pleb in the current state. Rather than the idea suggested above, group queues should be disabled for one battleground each week, and rotate. IE warsong this week, ab next week.
Make it so the big groups can keep doing their thing, but make them fight each other. Both factions have em, and both factions do the same queue dodging pug farming thing that makes the rest of us want to stop playing.
