Couple questions:
1.) Does it make any difference whether you're in passive or aggressive mode in these, or do raiders automatically hunt and escorts automatically hunt for the hunters?
2.) Does it help to make convoys for defensive purposes and/or if you're commerce raiding?
3.) How are speed and evasion/detection values factored in? Frigates have the fastest speed coeff and evade/patrol values so are they the best commerce raiders/commerce raider hunters?
4.) Do transports bring back more supplies than brigs? Could the Confederacy conceivably form its own convoy system with regular transports and steam frigates?
