The same way you boost any barrack or Hero,
When I'm using BAM and I have all 4 & both dark barracks boosted, I'm attacking every 5-7 minutes, by the time I'm back to my base after I attacked already My troops are all ready for me to go into battle again, But request every 20 Minute means 3-5 matches I'm going in clan-less because sometime it take a little to get full..
Not a major idea, but it would improve gameplay.
