Corsairs have a different situation. Population problems int he affirmative. Outcasts have the exsact opposite issue. It would stand to reason indentured would use the transports and it might become a common sight but trafficking from other factions and mostly junkers has been such a common sight I think its more part of the roleplay.
That being said ive seen outcasts get ahold of 5 kers easily enough and recently the pilgrim has become available in OC systems.. likelt the thing would be at MAX 4300 with heavy armor and a retarded number of turrets.
