I agree with Ordo, Why? This seems like adding units for the sake of adding units.
P.S. Mercenaries don't make a mod good or bad.
That's true it doesn't make a good or bad mod , it can make it more interesting if you can capture certain planets that produces specialized units.
Yes, I don't think they would really add anything new or ground breaking, economically they don't make sense either since the appeal of a Mercenary army is they are cheaper and faster to produce than professional troops you keep on retainer, which isn't a factor with the cost of standard light units(all mercenaries really would have in the SW universe) being so affordable already.
I disagree , I would not say the mando's and bounty hunters where cheap and they did specialized hits against certain targets,Wookies and trandosans fought for different sides during the star wars universe(the old universe before Disney screwed it up) and pirates and hutts raided fleets and also worked for different sides to and no one really knows what happened to ig88's army he was making.
Making some small units of a specialized merc squad available to sabotage (ships in orbit or buildings),raid the enemy in space or on the ground,Maybe put a bounty on a enemy (like in sins),or if you could make foc like the old rebellion game and add diplomacy , insurgency and quelling riots that would be awesome to.Making some ships and ground forces available only on specific worlds if you capture them.Not saying to add lots of new units , just certain ones would be cool.
Well thats my 2 cents worth
