Would make anything more than PS 1 horrendously overpriced. You're already paying for the high PS- that's part of a ship's cost.The best mercenaries charge more than the bad ones. "Pay squad points equal to the normal cost, plus extra points equal to the pilot's skill" You can get a Binayre Pirate for cheap, but if you want Talonbane, it's going to cost you. This might help with the balancing.
Yep. But otherwise I would fly scum with everything. If there isn't an increased cost, then the factions start to just blend together way too much. I like the idea of being able to hire mercenaries, but I also like to keep scum as a distinct faction.
