That begs 2 questions then.
1) Why does it show progress toward a warlord win whenever you conquer a homeworld?
2) How on earth is someone supposed to get a warlord win without being a warlord? You guys have said on here that you odn't have to get your own specialty's victory, you can get others. But if you have to destroy homeworlds for warlord, that means only a warlord can do it as only they can build the planet killer. Only researchers can create solar core taps to make black holes to get their victory. That would basically mean anyone can get a trader victory (excluding the fact that NO one can get it because the requirements are ridiculously unbalanced), but traders can ONLY get their own victory or the artifacts. Also, that brings up the question of how SG7 was able to win on Aruru with the warlord victory as a researcher by capturing homeworlds...
