It'll probably make it quicker to get into a BG too for those who are using it to suppliment XP while levelling a new team. When I was doing my shamans, I'd initially hoped to level solely from BGs, but found the queue time to make that a no go. So I'd join the queue and then continue questing. With it being random, you'll get into one quicker in theory. Granted it might not yield as much xp/honour as doing AV over and over, but will still get you in.
