I was the one who proposed this change, specifically change from the current Defensive Stronghold mandate to the Capitalism Reigns mandate. The reason behind it is that one of the strengths of Metal Lords was a very active and very successful corporate recruitment drive, based on this mandate. Basically we told various companies that if they started or moved interest within our space they would be able to jump to Tier 3 immediately, which lead to having them more involved within our faction and recuirment of very valuable members like Ra and Aeshi Tillian.
If the FWC would switch to Capitalism Reigns we would be able to assimilate this recruitment drive into the faction and help boost your numbers more efficiently, as a matter of fact I already received a couple of new members brought in by the interest from this mandate, one of them being [member="Errreembuhr"], so changing to this mandate would have immediate effect by allowing for Err and another new recruit to gain a tier within their companies just by setting up shop within FWC space.
As to the Defensive Stronghold, it's a good mandate if FWC was under siege, but we are one of the few nations that officially did not declare a side in the so called Great Galactic War, I do not see FWC becoming a target in the nearby future, not to mention, as GA showed, having Defensive Stronghold mandate does not actually help that much with defense of their territory. At this point it's not about how many allies you can summon or how many characters participate in the invasion if you have the minimal amount required, what matters more is how well the allies work together and the story they write.
