So I'm currently playing as advent right now, and I'm having trouble grouping my fleets.  I like to group my cap ships and guardians so they stay close.  However, even when I disable the auto join fleet, my illums still will crowd around the capital ship.  This isnt bad normally in big battles, but it becomes a pain when I am trying to ram them down the enemy's throat and they just run back to the cap ship after.  Any ideas/tips?
